Description
本发明涉及一种冷成形用的,并提供优良耐磨性的钢。
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 <200ppm <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 <50ppmTi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。
