含稀土双相不锈钢合金
摘要：
本发明公开了一种含稀土金属双相不锈钢合金，该不锈钢合金的组份及质量百分比(Wt％)为：C：0.08～0.12，Mn：1.00～2.50，Si：1.50～3.50，S：0.01～0.03，P：0.015～0.035，Ni：2.00～4.00，Cr：18.00～20.00，N：0.05～0.20，Al：0.10～0.28，Ti：0.20～0.50，Re：0.01～0.20，杂质≤1.00，余量为Fe。该不锈钢经过包括配料、熔化、造渣、预脱氧、终脱氧、出钢浇铸等步骤而成。该不锈钢不仅具有高的耐蚀性及良好的机械性能及工艺性能；而且能降低镍、锰元素的含量，从而使钢材成本大幅减少，相比现在通用的304、316不锈钢而言性价比更高。？
摘要（英）：

The invention discloses a two-phase stainless steel alloy containing rare-earth metals. The stainless steel alloy comprises the following components by weight percentage (wt%): 0.08 to 0.12 C, 1.00 to 2.50 Mn, 1.50 to 3.50 Si, 0.01 to 0.03 S, 0.015 to 0.035 P, 2.00 to 4.00 Ni, 18.00 to 20.00 Cr, 0.05 to 0.20 N, 0.10 to 0.28 Al, 0.20 to 0.50 Ti, 0.01to 0.20 Re, lower than or equal to 1.00 impurities and the balance of Fe. The stainless steel alloy is prepared through the following steps: sorting, melting, slagging, pre-deoxidizing, final-deoxidizing, tapping, casting and the like. The stainless steel alloy not only has high corrosion resistance and good mechanical and technological properties, but also reduces the content of nickel and manganese, thereby greatly reducing the cost of steel materials and ensuring higher price-to-performance ratio than that of the conventional 304/314 stainless steel.
