Austenitic Stainless Steel

Type 304 stainless steel is an austenitic alloy containing 18% chrome and 8% nickel.

The alloy has a lower carbon content which minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. Weldability and forming properties of Type 304 are excellent whilst machinability is reasonable. The alloy also benefits from very good drawability. A combination of low yield strength and high elongation allows for the forming of complex shapes, although it should be noted that the material hardens rapidly. Type 304L is the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm).

Key Features:
