304 stainless steel, also known as UNS S30400, is made with a special mix of materials. It includes 0.08% Carbon, 0.75% Silicon, 2.0% Manganese, 0.030% Sulfur, and 0.045% Phosphorous. This steel type, according to ASTM A312 / A213 SS TP 304 standards, has strong physical properties: it has a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa, a maximum Rockwell B hardness of 92, and a maximum Brinell hardness of 201. Chromium is the key element that makes steel “stainless” by forming a protective layer on the steel surface. No other element can replace chromium in this role.

All our 304 stainless steel products at Steel Alloys meet industry quality standards and offer features like strong construction, precise dimensions, and long service life. Steel alloys uses high-quality raw materials and the latest technology to ensure excellent performance and reliability in all our stainless steel products.
