摘要

研究了1000～1240℃淬火

以及1100℃淬火+200～580℃回火对25 kg真空感应炉冶炼的Cr8WMo2V2SiNb钢(%:0.96C、1.11Si、7.79Cr、1.79Mo、2.16V、0.96W、0.60Nb)Φ13 mm锻材的淬火组织和晶粒度

淬-回火组织、硬度和冲击功的影响。结果表明

Cr8WMo2V2SiNb钢1 100℃淬火后的硬度HRC值为64.5;1100℃淬火+520℃回火有明显二次硬化效应

硬度达到最大值-HRC62.5

并有较好的韧性

冲击功为8.7 J。

Abstract

Effect of quenching treatment at 1 000 ~ 1 240 Y and quenching at 1 100 °C + tempering at 200 〜580℃ treatment on quenched structure and grain size

quenched-tempered structure

hardness and impact energy of 613 mm forged product of steel Cr8WMo2V2SiNb (% ： 0. 96C

1. HSi

7. 79Cr

1. 79Mo

2. 16V

0. 96W

0. 60Nb) melted by a 25 kg vacuum induction furnace

has been studied. Results show that with 1 100 ℃ quenching

the hardness HRC value of steel Cr8WMo2V2SiNb is 64. 5

with 1 100 ℃ quenching + 520 ℃. tempering the steel has obvious secondary hardening effect

and the hardness of steel is coming to maximum i. e. HRC62. 5 with better toughness i. e. impact energy 8. 7 J.
