What Is 18/8 Stainless Steel?

 

18/8 stainless steel is a widely used grade of austenitic stainless steel, named for its chemical composition: approximately 18% chromium and 8% nickel. It is most commonly associated with Type 304 stainless steel, which is one of the most popular and versatile stainless steel grades in industrial and consumer applications. The balanced alloy formulation provides an ideal combination of corrosion resistance, strength, and formability, making it a top choice for CNC machining services across various sectors.

 

The 18% chromium content contributes to excellent oxidation and corrosion resistance by forming a passive chromium oxide layer on the surface, which helps protect the metal from rust and chemical attack. The 8% nickel enhances the material’s ductility and toughness, especially in low-temperature environments, and supports the formation of the austenitic structure, giving the steel its non-magnetic behavior in annealed conditions.

 

From a CNC machining perspective, 18/8 stainless steel is favored for its relatively good machinability compared to other stainless steels, especially those with higher nickel or molybdenum content. While not as free-machining as ferritic or martensitic grades, it offers a solid balance between formability and resistance to tool wear, making it suitable for complex geometries, tight tolerances, and both roughing and finishing operations.

 

Common applications of 18/8 stainless steel include:

• Kitchen equipment (sinks, countertops, cookware)

18/10 stainless steel is a premium-grade austenitic stainless steel alloy containing approximately 18% chromium and 10% nickel. Like 18/8, it falls under the Type 304 family and shares the same base composition, but the increased nickel content gives 18/10 stainless steel enhanced corrosion resistance, improved durability, and a shinier, more attractive surface finish. It is especially prized in industries that prioritize long-term resistance to rust, staining, and chemical attack—such as food service, medical, and decorative product manufacturing.

 

The 18% chromium provides the alloy with its fundamental corrosion resistance by forming a self-healing oxide layer on the surface. The 10% nickel boosts the alloy's structural stability and resistance to acids, alkaline solutions, and chloride-rich environments. As a result, 18/10 stainless steel is particularly suitable for high-end applications where performance, cleanliness, and aesthetics are critical.

 

While 18/10 stainless steel is highly desirable for its strength and beauty, it is generally more challenging to machine than 18/8 due to its higher nickel content. This increased toughness can lead to higher tool wear, more heat generation, and the need for slower cutting speeds and specialized tooling. For this reason, 18/10 stainless steel CNC machining parts require skilled programming, optimal cutting parameters, and advanced CNC machining services to ensure precision and cost-efficiency.

 

Typical uses of 18/10 stainless steel include:

• Luxury cookware and cutlery
• High-end kitchen appliances

• Decorative fixtures and architectural accents
• Food processing and serving equipment

Despite the increased machining complexity, 18/10 stainless steel remains a top choice for applications requiring a brilliant finish, superior corrosion protection, and long-lasting performance. CNC machining factories that specialize in stainless steel are well-equipped to handle the demands of 18/10 stainless steel, offering high-precision parts with aesthetic excellence and mechanical reliability.

 

 

 

 

 

What Is the Main Difference Between 18/8 and 18/10 Stainless Steel?

 

The key difference between 18/8 and 18/10 stainless steel lies in their nickel content—a small variation that significantly impacts corrosion resistance, durability, appearance, and machinability. Both belong to the Type 304 family of austenitic stainless steels, featuring 18% chromium as the corrosion-fighting backbone. However, while 18/8 contains approximately 8% nickel, 18/10 contains about 10%, giving it enhanced performance characteristics in certain applications.

 

This difference in nickel content may seem minor, but it influences several material behaviors. For instance, 18/10 stainless steel offers slightly superior corrosion resistance and a more polished, lustrous finish, which makes it preferred for high-end cookware, food equipment, and decorative items. On the other hand, 18/8 stainless steel is easier to machine, more cost-effective, and more than adequate for many industrial and consumer-grade applications.

 

Understanding this distinction is crucial when selecting a material for CNC machining. In machining environments, higher nickel content in 18/10 increases tool wear and cutting resistance, requiring more careful process control. Meanwhile, 18/8 stainless steel CNC machining offers a smoother and more economical machining experience, especially in high-volume production.

In summary, if corrosion resistance and appearance are top priorities, 18/10 is ideal. If cost, machinability, and general-purpose use are more important, 18/8 is the better choice.

In this section, we will explore and compare the mechanical and physical properties that affect their performance during and after CNC machining. This includes chemical makeup, tensile and yield strength, elongation, hardness, thermal conductivity, corrosion resistance, and surface aesthetics. Whether you're sourcing CNC machining parts for food processing, medical tools, or consumer products, this comparative breakdown will help guide informed material choices.

 

 

 

 

 

18/8 and 18/10 Stainless Steel: Chemical Composition

 

 

 

The chemical composition of stainless steel defines its corrosion resistance, formability, strength, and how it responds to CNC machining. Though both 18/8 and 18/10 are categorized under the same grade (Type 304), the small variation in their elemental makeup—particularly in nickel content—creates meaningful differences in performance and machining behavior.

 

Let’s explore each element's contribution to the material's characteristics and how it affects machining outcomes in CNC machining factories.

 

 

Chromium (Cr)

 

Both 18/8 and 18/10 stainless steels contain approximately 18% chromium. This element plays a critical role in the formation of the passive oxide layer that gives stainless steel its signature corrosion resistance. Chromium enhances hardness and oxidation resistance without compromising ductility, which is why both alloys perform well in corrosive environments like kitchens and industrial machinery.

 

 

Nickel (Ni)

 

Nickel content is the primary difference between these two stainless steels:

• 18/8 contains around 8% nickel, providing a good balance of corrosion resistance, ductility, and machinability.
• 18/10 contains 10% nickel, improving pitting resistance, surface luster, and overall toughness. However, this also makes it slightly more challenging to machine due to increased hardness and tool wear.

In CNC machining, higher nickel content can demand reduced cutting speeds, specialized tools, and greater cooling, which affects production efficiency and cost.

 

 

Carbon (C)

 

Both grades typically contain ≤ 0.08% carbon, ensuring high corrosion resistance while maintaining adequate strength. Carbon improves hardness but must be carefully controlled to prevent carbide precipitation, which can compromise corrosion resistance in welded components. From a CNC perspective, this level of carbon keeps both materials relatively easy to cut and shape.

 

 

Manganese (Mn)

 

Manganese levels usually range between 1–2%. It enhances hot working properties and stabilizes the austenitic structure. Manganese also aids in deoxidization during melting and can slightly improve toughness. It does not significantly affect machinability but contributes to the overall structural integrity of CNC-machined parts.

 

 

Silicon (Si)

 

Typically present in quantities around ≤ 1%, silicon acts as a deoxidizer and improves resistance to scaling at high temperatures. While it has a minor effect on mechanical performance, silicon does help maintain material stability during thermal CNC processes like high-speed milling and drilling.

 

 

Phosphorus (P)

 

Phosphorus content is controlled at ≤ 0.045%. It improves machinability to a small degree by increasing the material's brittleness slightly, which helps with chip breaking. However, excess phosphorus can reduce ductility, so it is carefully managed in both alloys to maintain formability and toughness.

 

 

Sulfur (S)

 

Although not mentioned directly in your outline, it’s worth noting that sulfur may be present in trace amounts (≤ 0.03%) to enhance machinability. However, it can lower corrosion resistance, so its presence is minimal in high-grade 18/8 and 18/10 stainless steel used for CNC machining.

Both 18/8 and 18/10 stainless steel are part of the austenitic 304 stainless steel family, and they exhibit very similar temperature resistance due to their comparable chromium content and overall alloy structure. Typically, both materials can withstand continuous operating temperatures up to approximately 870°C (1600°F) and intermittent exposure up to around 925°C (1700°F) without significant loss of mechanical properties or corrosion resistance.

 

Temperature Resistance Comparison:

 

18/8 Stainless Steel:

• Continuous use up to ~870°C
• Intermittent exposure up to ~925°C
• Maintains structural integrity and corrosion resistance within these ranges

18/10 Stainless Steel:

• Continuous use up to ~870°C
• Intermittent exposure up to ~925°C
• Slightly better oxidation resistance due to higher nickel content, which may marginally enhance high-temperature stability in some environments

 

Does 18/8 Withstand Higher Temperatures?

 

No significant difference exists between the two grades in terms of maximum operating temperature. The extra nickel in 18/10 stainless steel provides improved resistance to oxidation and scaling at elevated temperatures, but this does not drastically affect the maximum temperature the material can safely handle. Both materials perform well in high-temperature applications typical of kitchenware, heat exchangers, and industrial equipment.

 

For CNC Machining Applications:

 

From a machining and application standpoint, neither 18/8 nor 18/10 stainless steel offers a clear advantage regarding temperature tolerance. Instead, selection should focus on corrosion resistance, durability, and cost-effectiveness depending on the environment where the parts will be used.

In conclusion, neither 18/8 nor 18/10 stainless steel distinctly withstands higher temperatures; both perform reliably in the same temperature ranges typical of their common applications.

 

 

 

Is 18/8 Stainless Steel More Magnetic Than 18/10 Stainless Steel?

 

Both 18/8 and 18/10 stainless steel are primarily austenitic stainless steels, belonging to the Type 304 family, which is known for its non-magnetic or very weakly magnetic properties in the annealed (fully heat-treated) state. However, small differences in their composition and processing can affect their magnetic behavior slightly.

 

Magnetic Properties Comparison:

 

18/8 Stainless Steel:

• Typically exhibits very weak magnetic response or is essentially non-magnetic when annealed.
• Magnetic permeability may increase slightly if the steel is cold-worked or mechanically deformed, due to the formation of small amounts of martensite (a magnetic phase).

18/10 Stainless Steel:

• Similarly, it is generally non-magnetic in the annealed state.
• Slightly higher nickel content (10% vs. 8%) tends to stabilize the austenitic phase better, making 18/10 stainless steel less likely to become magnetic under mechanical stress or cold working.

 

Practical Implications:

• Both materials are considered non-magnetic for most practical applications, which is important in fields like electronics, food processing, and medical equipment where magnetism must be minimized.
• In CNC machining, any induced magnetism from forming or machining is usually minimal and does not affect the functionality of most parts.
• If absolute non-magnetic behavior is required, specific low-magnetic grades or post-machining heat treatments are considered instead.

 

 

Summary Table: Magnetic Properties of 18/8 vs. 18/10 Stainless Steel

 

 

 

 

In conclusion, 18/10 stainless steel tends to be marginally less magnetic than 18/8 stainless steel, thanks to its higher nickel content. Both are considered non-magnetic for most industrial uses, but 18/10 is slightly preferred when magnetism must be minimized.
