904L Manufacturering Technology
Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high alloy austenitic stainless steel with low carbon content, which has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosive environments. It has a high chromium content and sufficient nickel content. The addition of copper gives it strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not prone to corrosion spots and cracks, and its resistance to pitting corrosion is slightly better than other steel grades. It has good machinability and weldability, and can be used for pressure vessels.
Brand and standard:
UNS N08904 (a standard jointly designed by the American Society of Automotive Engineers and the American Society for Testing and Materials in 1967), DIN1.4539 (a German standard), ASTM A240 (an American Society for Testing and Materials standard; the new standard classifies it as a stainless steel series, while the original standard ASME SB-625 classifies it as a nickel based alloy series), and SUS890L.
Metallographic structure of 904L stainless steel:
904L is a completely austenitic structure, and compared to austenitic stainless steel with high molybdenum content, 904L has a significant impact on ferrite and α The precipitation of phases is not sensitive.
Physical and mechanical properties:
Density: 8.0g/cm3. Tensile strength: σ B ≥ 520Mpa. Elongation: δ≥ 35%. Corrosion resistance of 904L stainless steel
