Product of description
904L stainless steel material is a super austenitic stainless steel material, grade: 00Cr20Ni25Mo4.5Cu, UNS: N08904, EN: 1.4539, is a high-alloyed austenitic stainless steel with very low carbon content. Very good corrosion resistance, designed for environments with harsh corrosive conditions. It has high chromium content and sufficient 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 resistant to corrosion spots and cracks. The pitting resistance is slightly better than other steel types, and it has good machinability and weldability. Non-magnetic in solid solution state;
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:4.0-5.0. 904L The minimum value of the mechanical properties of the alloy at room temperature: alloy and state: 926, tensile strength (Rm N/mm2): 490, yield strength (RP0.2N/mm2): 216, elongation A5%: 35.
