供应耐酸钢【904L钢板】低碳高镍不锈钢
904 l belong to low carbon high nickel, molybdenum austenitic stainless steel 904 l stainless acid-resistant steel, for the introduction of French h. S proprietary materials of the company. Has the very good activation and passivation shift ability, excellent corrosion resistance, in the oxidizing acid such as sulfuric acid, acetic acid, formic acid, phosphoric acid have good corrosion resistance of 904 l steel plate, in neutral chlorine ion medium has the very good pitting resistance, at the same time has good resistance to crevice corrosion and stress corrosion resistance. Used in various concentration of sulfuric acid under 70 ℃, under ordinary conditions of any concentration, temperature resistance of acetic acid and formic acid and acetic acid in mixed acid corrosion resistance is very good also. A low carbon high alloy austenitic stainless steel, in dilute sulphuric acid have good corrosion resistance, specially designed for harsh environment corrosion conditions. Has the high chromium content and plenty of nickel content, the addition of copper makes it have strong ability to resist acid, especially for chloride clearance corrosion and stress corrosion cracking are highly resistant, not easy to appear, erosion and fracture pitting resistance slightly better than other steel grade, good machinability and weldability, can be used for pressure vessels.
904LXX马氏体不锈钢典型的基体金属显微组织为回火马氏体。这种低碳回火马氏体组织具有很高的强度和韧性。根据含镍量的不同、热处理条件的差异，一些牌号的XX马氏体不锈钢基体显微组织中可能会出现10%～40%的细小弥散状残留奥氏体。对于含铬16%等X的XX马氏体不锈钢，显微组织中可能出现少量的δ铁素体。为了获得理想的细晶粒回火马氏体，在钢板交货之前一般都经过淬火加回火处理。
