904L stainless steel is a kind of super austenitic stainless steel, with the brand name of 00cr20ni25mo4.5cu, UNS: N08904, EN: 1.4539. It is a kind of high-alloy austenitic stainless steel with low carbon content, which has good corrosion resistance in dilute acid, and is specially designed for the harsh environment. With high chromium content and enough nickel content, the addition of copper makes it have strong acid resistance, especially high resistance to chloride crevice corrosion and stress corrosion cracking, and it is extremely difficult to have corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels, and it has good machinability and weldability. Solid solution state is nonmagnetic;

Chemical composition of 904L:% C≤0.03, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.03, Ni:23.0-25.0, Cr:18.0-20.0, Mo:3.0-4.0, Cu: 4.0. The minimum values of mechanical properties of 904L alloy at room temperature: alloy and state: 926, tensile strength (Rm N/mm2):490, yield strength (RP0.2N/mm2):216, elongation A5 %:35.
