钢采用氧气转炉、电弧炉或平炉冶炼，几种方法可以单独使用，也可以组合使用。在征得买方同意后，还可以采用其他在技术上等效的炼钢方法。钢水应脱氧后浇铸。除非咨询和定单另有规定，选用炼钢方法应由生产厂自行决定。根据要求，所采用的炼钢方法应通告买方。表3所列牌号不得采用纯氧转炉法。1.2 钢管采用非焊接法制造，可以用冷加工或热加工方法制造。冷加工的钢管应在整个长度上进行标准热处理。正火操作应当在高于相变点Ac3的温度下进行。热加工的钢管应进行标准规定的热处理。但是，如果钢管厚度不大于20mm，则应考虑采取一些补充措施。2 牌号和化学成分钢的牌号和化学成分(熔炼分析和成品分析)见表1、表2和表3。除为了脱氧而带入钢中的一些元素外，不能随意添加各表中未列入的元素。根据咨询和定货单中的要求，可检验钢管的化学成分。3 力学性能交货状态钢管的纵向力学性能见表4、表5、表6。4 物理性能各牌号钢的弹性模量、平均线膨胀系数和热导率见表7、表8和表9。5 尺寸、单位长度重量及偏差5.1 钢管的尺寸和单位长度重量见表10、表11、表12和表13。根据订货协议，可以参照标准规定提供一些中间厚度的钢管。表1 非合金钢牌号和化学成分 %牌号熔炼或成品CMnPSSiCu 1） Sn
