904L钢板#不锈耐酸钢904L低碳高镍钢
904 l stainless steel is low carbon and high nickel, molybdenum, 904 l austenitic stainless acid-resistant steel proprietary material for h. S company in France. Has the very good activation - 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 medium containing chloride ions has the very good resistance to pitting corrosion, and has good resistance crevice corrosion and stress corrosion resistance. Applicable to various concentrations of sulphuric acid under 70 ℃, under ordinary conditions of pressure resistance to any concentration, temperature 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 the dilute sulphuric acid have good corrosion resistance, specially designed for harsh environment corrosion conditions. With high content of chromium and nickel content enough, the addition of copper make it has strong acid resistance, especially for chloride clearance corrosion and stress corrosion cracking are highly resistant, not easy appeared pitting spots and cracks, pitting resistance
904L不锈钢属低碳高镍、钼奥氏体904L不锈耐酸钢，为引进法国H•S公司的专有材料。具有很好的活化—钝化转变能力，耐腐蚀性能极好，在非氧化性酸如硫酸、醋酸、甲酸、磷酸中具有很好的耐蚀性904L钢板，在中性含氯离子介质中具有很好的抗点蚀性，同时具有良好的抗缝隙腐蚀及抗应力腐蚀性能。适用于70℃以下各种浓度硫酸，在常压下耐任何浓度、任何温度的醋酸及甲酸与醋酸的混酸中的耐腐蚀性也很好。是一种含碳量低的高合金的奥氏体不锈钢，在稀硫酸中有很好抗腐蚀性，专为腐蚀条件苛刻的环境而设计。具有较高的铬含量和足够的镍含量，铜的加入使它具有很强的抗酸能力，尤其对氯化物间隙腐蚀和应力腐蚀崩裂有高度抗性，不易出现蚀损斑和裂缝，抗点蚀能力略优于其他钢种，具有良好的可加工性和可焊性，可用于压力容器。
