Stainless steel 304 is an austenitic stainless steel. It contains high nickel content. Typically between 8 and 10.5% by weight. It contains about 18 to 20% by weight of high chromium. Grade 304 stainless steel has low carbon content. It can minimize the chromium carbide precipitation produced by welding and the sensitivity of the alloy to intergranular corrosion.
The alloy also exhibits excellent toughness, even down to cryogenic temperatures. On the other side of the spectrum, in terms of oxidation resistance. It will continue to show significant scaling.
It is the same as most other austenitic grades. Type 304 can be easily welded using common fusion and resistance methods.
