新型马氏体不锈钢1Cr10Co6MoVNbN热加工工艺研究

Research on the Processing Technology of New Type of Martensitic Stainless Steel 1Cr10Co6MoVNbN

1Cr10Co6MoVNb是一种新型马氏体热强不锈钢,用于某发动机高压压气机转子、盘、叶片和密封圈等重要部件,是国产化研究的重要材料。通过分析计算锻造和装炉温度、加热速度、保温时间等参数,制订出理想的锻造加工工艺,并在进口2 000t快锻机上进行了锻造成型工艺试验。结果表明,制订的锻造生产工艺合理可行,钢材锻后具有良好的低倍、断口组织,淬回火状态下具有良好的综合力学性能,超声波探伤100%达到技术要求,满足了国产化用材的需要。

1Crl0Co6MoVNb is a new type martensite stainless steel that was used for compressor rotor, blade, disc and other important component of an engine high pressure seals. It is the domestic research material. In this paper, by analysis and calculation on the forging temperature, furnace temperature, heating rate, holding time and other parameters, the forg-ing forming process was tested on a localization engine material 1Crl0Co6MoVNbN steel with 2 000t imported quick forging machine. Trial results showed that the forging production process was reasonable and practicable, it can get good macro- structure and fracture organization after forging, it had nice synthetic mechanical property under the state of quenching and tempering, its UT meet the technical requirements 100%, it can meet the domestic timber requirements completely.
