Abstract
提出了一种适合用于冷成形及经合金熔化及精炼而得到的钢，其特征在于此合金成分(重量%)如下：C 0.80-1.50%，Mn＜1%，Si＜1%，P≤0.030%，S≤0.005%，Cr 6.25-9%，Ni＜0.50%，Mo 10-3%，Al＜0.15%，V 0.20-0.40%，Nb 0.60-1.5%，N＜150ppm，O＜50ppm，Ti或Zr 500-1500ppm，余为Fe及生产此金属时特有的杂质。
Description
本发明涉及一种冷成形用的，并提供优良耐磨性的钢。
国际专利申请公开WO91/00371A公开了一种具有下述组成的钢，按重量百分比计：C 0.35-1.2，Mn 0.3-3，Si 0.3-2，Cr 5.0-11.5，Mo 0.3-5.0，Nb 0.4-5.0，V 0.3-3.0，任选的Ta 0.01-0.2，Ti 0.01-0.2，Ni 0-3，其余为铁和不可避免杂质。
本发明目的是将5％铬钢的优点和12％莱氏体铬钢的优点结合在一起。本发明提供了一种新型钢种，它具有以下性能的组合：最佳耐磨性，优良韧性，维持良好渗氮硬度，因此尤其适用于要求尺寸稳定性的硬表面。
这种钢是通过将钢熔化和精炼而得到的，其特征在于该合金的成分(重量％)如下：
优选范围 宽的范围
C 1-1.20％ 0.80-1.50％
Mn 0.30-0.50％ ＜1％
Si 0.80-1％ ＜1％
P ≤0.020％ ≤0.030％
S ≤0.005％ ≤0.005％
Cr 8-8.50％ 6.25-9％
Ni ＜0.30％ ＜0.50％
Mo 2-2.30％ 1.80-3％
Al ＜200pp ＜0.15％
V 0.20-0.40％ 0.20-0.40％
Nb 0.60-0.90％ 0.60-1.5％
N ＜130ppm ＜150ppm
O ＜30ppm ＜50ppm
Ti或Zr 500-1000ppm 500-1500ppm其余为Fe及生产此金属时特有的杂质。
此钢是经电熔化，接着在加热的钢包中精炼，真空脱气及重熔过程而加工成的。
在此钢中，C和Nb形成铌的碳化物，而Ti或Zr便于获得自形的铌的碳化物。形成铌的碳化物的化学计算关系是约1％的Nb对0.12％的C。过量的C被钢中的Cr、Mo和V含量平衡。
本发明的钢的硬度大于60Hrc。它显示出以下性能的组合：耐磨性、机加工性和以前从来得到过的韧性。
通过按Charpy测试法测定韧性。在1050℃下处理7×10×55mm参考试样、止于油中，接着是2小时、560℃的退火。就超过或等于60Hrc的硬度而言，它显示出等于或大于40焦耳的断裂功。
本发明的冷成形钢改善了耐磨性，它包括以下三种形式：
—明显改善的磨耗。
—由于该钢优良的韧性而明显改善的去皮损耗，
—也明显改善的粘附损耗。
本发明不只限于所述的和所述的实施方案，而覆盖所有可能的变化。
