Type 304 is the most versatile and widely used stainless steel. It is part of the austenitic stainless steel family and is often referred to as 18/8, which signifies its composition of 18% chromium and 8% nickel. It has excellent corrosion resistance in various environments and is highly durable.
Alloy 304/304H can be easily welded and processed by standard shop fabrication practices.

The alloy is quite ductile and forms easily. Cold working operations will increase the strength and hardness of the alloy and might leave it slightly magnetic.
Working temperatures of 1652–2102°F (750–1150°C) are recommended for most hot working processes. For maximum corrosion resistance, the material should be annealed at 1900°F (1038°C) minimum and water quenched or rapidly cooled by other means after hot working.
Alloy 304/304H is subject to work hardening during deformation and is subject to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling and powerful rigid equipment.
