摘要

设计的试验钢（0.45C-12.5Cr-0.41Mo-0.22V钢和0.85C-10.5Cr-0.91Mo-0.25V钢）由50 kg真空感应炉熔炼并锻造成试验用钢样。试验研究了淬火温度（950~1150℃）、回火温度（一次回火200400℃

二次回火500~600℃）对钢的组织、强度、延伸率、硬度和冲击功的影响。结果表明

1 050℃淬火+500℃二次回火处理后0.45C-12.5Cr-0.41Mo-0.22V钢的性能最佳:抗拉强度为1 712.3 MPa、屈服强度为1 476.5 MPa、延伸率为7.8%、HRC硬度值为69.3以及冲击功为7.3 J。二次硬化会提升模具钢的硬度值

而回火过程中碳化物的长大以及分布不均匀容易造成冲击韧性的降低。试验的新型不锈钢模具的强度指标高于普通商用模具钢42Cr3Mo2MnV1。

Abstract

The designed tested steels (steel 0.45C-12. 5Cr-0. 41 Mo-0. 22V and steel 0. 85C-10. 5Cr-0. 91 Mo-0. 25V) are melted by a 50 kg vacuum induction furnace and forged to tested specimen. The effect of quenching temperature (950 ~ 1 150 ℃)，tempering temperature (once tempering at 200 ~ 400 ℃. and double tempering at 500 ~ 600 ℃)on structure

strength

elongation

hardness and impact energy of steels is tested and studied. Results show that the properties of steel 0.45C-12.5Cr-0.41 Mo-0. 22V quenched at 1 050 ℃+ double tempered at 500 ℃ are best： tensile strength 1712.3 MPa

yield strength 1 476.5 MPa

elongation 7. 8%

HRC hardness value 69. 3 and impact energy 7. 3 J. The hardness value of die steel increases by secondary hardening

but during tempering process the carbides in steel grow up with uneven distribution easily led to impact toughness of steel decreasing. The strength index of tested new stainless die steels is high than that of normal commercial die steel 42Gr3 Mo2MnVl.
