Stainless Steel Alloy 304 Machined Parts
Cox Manufacturing has a reputation for machining quality parts from 304 Stainless Steel. When it comes to 304 stainless steel machining, we can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Stainless steel alloy 304 is an extremely popular low-cost alloy, ideal for parts that require forming or welding. It has excellent corrosion, oxidation, and heat resistance and is the most weldable of any steel alloy. 304 stainless steel is not magnetic.
304 has a machining cost factor of 5.0 when compared to steel 12L14. It is excellent for welding and produces tough and ductile welds. 304 Stainless Steel machining does not respond to heat treatment, but can be cold worked to increase tensile strength and hardness. Annealing is recommended after forging and cold working.
Industries & Applications
