摘要： A newly proposed steel consists of 8.0-35.0 wt. % Cr, 0.05-1.20 wt. % C, 0.05-3.0 wt. % at least one of Ti, Nb, Zr, V and W and the balance being essentially Fe and has the structure that a total amount of Ti, Nb, Zr, V and/or W carbide precipitates distributed in a steel matrix is adjusted to 0.l wt. % or more. The steel is bestowed with excellent abrasion-resistance by distribution of carbide precipitates. These carbides have nearly the same hardness as hard particles such as alumina and silicon carbides which causes abrasive abrasion. Due to such excellent abrasion-resistance, a weaving machine member, a sewing needle, an agricultural machine member such as a mowing tooth or a cutter blade made of the steel can be used over a long period.
摘要翻译：新提出的钢包括8.0-35.0wt。％Cr，0.05-1.20wt。％C，0.05-3.0重量％％Ti，Nb，Zr，V和W中的至少一种，余量基本上为Fe，并且具有将分布在钢基体中的Ti，Nb，Zr，V和/或W碳化物析出物的总量调整为 0.1wt。％或者更多。钢通过碳化物沉淀物的分布赋予优异的耐磨性。这些碳化物具有与硬质颗粒（例如氧化铝和碳化硅）几乎相同的硬度，这导致研磨磨损。由于这种优异的耐磨性，可以长时间使用织造机构，缝纫针，割草机等农业机械部件或由钢制成的切割刀片。
