通过对1Cr11Ni2W2MoV钢的三大生产厂的电渣重熔料及真空自耗重熔料的试验研究,发现该钢经电渣重熔后,合理的回火温度为560~580℃和640~660℃,以避免第一回火脆性和第二回火脆性、而该钢真空自耗重熔后不存在第二回火脆性。
Through the test and study of the electroslag remelting material and the vacuum consumable remelting material in the three production plants of 1Cr11Ni2W2MoV steel, it is found that the reasonable tempering temperature of the steel after electroslag remelting is 560-580 ° C and 640-660 ° C So as to avoid the first temper embrittlement and the second temper embrittlement, and the second temper embrittlement does not exist after the steel vacuum consumable remelting.
