2025 07 10 18/8, 18/10, and 18/0 stainless steel differ mainly in their nickel content, affecting corrosion resistance, durability, and magnetic properties. 18/10 offers the highest corrosion resistance and shine, 18/8 balances cost and performance, while 18/0 is more affordable but less durable. Choosing the right grade depends on application, environment, and machining requirements.

VMT 2025 07 09 18/8 stainless steel is generally more suitable for CNC machining than 18/10 due to its slightly lower nickel content, which improves machinability while still offering strong corrosion resistance. However, 18/10 provides superior durability and shine, making it ideal for parts requiring higher aesthetic value.

VMT 2025 07 08 Composite materials are engineered by combining two or more distinct materials — typically a matrix and a reinforcement — to create a material with superior mechanical, thermal, or chemical properties. Composites are used across industries for lightweight, high-strength, and corrosion-resistant parts.

VMT 2025 07 07 MIG/MAG welding are two arc welding methods widely used in CNC machining parts manufacturing. MIG uses inert gas for non-reactive shielding, ideal for non-ferrous metals, while MAG uses active gas suitable for ferrous metals. The key difference is the shielding gas type. Both offer high productivity and adaptability in welding CNC machining parts.

VMT 2025 07 04 Fit H7 is a standard tolerance grade for holes commonly used in CNC machining parts and assemblies. It specifies the permissible size variation with a zero lower deviation and a positive upper deviation depending on the nominal size. Understanding H7 tolerance ensures precise component fits, improving product quality and performance in CNC machining factories.

VMT 2025 07 03 18/8 stainless steel is an austenitic alloy composed of approximately 18% chromium and 8% nickel. It offers excellent corrosion resistance, strength, and workability, making it ideal for food-grade, medical, and industrial applications. Often equivalent to 304 stainless steel, it is widely used in CNC machining services to produce hygienic, durable, and visually appealing stainless steel CNC machining parts.
