Description
SUS304 material is a Japanese JIS standard and the most commonly used stainless steel, containing 18% Cr and 8% Ni. It can maintain good strength and heat resistance in high temperature and low temperature environments, and also has good corrosion resistance, weldability, cold workability and mechanical properties in the mild atmosphere. SUS is the first letter of “Steel Use Stainless” written in English. The stainless steel number consists of three digits, the 300 series is austenitic stainless steel, and the 400 series is ferritic or martensitic stainless steel. The following are the datasheets of SUS304 chemical composition and properties, such as melting point, density, tensile strength, elongation, modulus of elasticity, specific heat, coefficient of thermal expansion, thermal conductivity, electrical resistivity, magnetic properties and so on.
