摘要/Abstract

摘要： S31803奥氏体-铁素体双相不锈钢(%:0.03C、22.05Cr、5.23Ni、3.10Mo、0.16N)合金含量高，氧化层中所含的合金元素多，氧化物结构复杂，不易酸洗。通过正交试验得出H2SO4220g/L,NaCl 30 g/L,添加剂10 g/L, 在60 ℃平均酸洗时间57.2 min,使酸洗后的钢板表面色泽均匀，酸洗合格率达100%。

Abstract: Due to higher alloy content in steel,plenty of alloy element in oxide layer and complexity of oxide struc- ture,there are some trouble in pickling process for S31803 austenite-ferite duplex phase stainless steel(0.03C,22.05Cr, 5.23Ni,3. 10Mo,0. 16N).Iwas obtained by orhogonal test that with pickling solution H2SO4220g/L,NaCl 30 g/L, addition agent 10 g/L at 60 ℃ for average pickling time 57.2 min,after pickling the colour and gloss of plate surface was uniform and up to standard rate was 100%.
