文章附图

  310S(0Cr25Ni20/0Cr25Ni20Si2),耐热不锈钢,国内牌号0Cr25Ni20,美国牌号SA213/TP310S,俗称310S,又称2520,双相不锈钢,用于耐高温炉管制造。SA213/TP310S的化学成份(%):

  Ni 镍 :19.00-22.00

  Cr 铬: 24.00-26.00

  Si 硅 <= 1.50

  Mn 锰 <= 2.00

  C 碳 <= 0.08

  S 硫 <= 0.030

  P 磷 <= 0.035

  制作办法与无缝钢管根本共同,所用钢材按GB14975-94《不锈钢无缝钢管》规则,由0Cr13,1Cr13,2Cr13,3Cr13,1Cr17Ni2,1Cr25Ti,1Cr21Ni5Ti,00Cr18Ni10,1Cr18Ni9,1Cr18Ni9Ti,00Cr17Ni14Mo2,0Cr18Ni12Mo2Ti,1Cr18Ni12Mo3Ti,1Cr23Ni18,1Cr18Ni11Nb等钢号制作. 用处:不锈耐酸无缝钢管广泛用于石油、化工、管道和各种用处的不锈、耐酸钢结构零件,应确保钢材的化学成分和物理性能。
