1Cr12Ni3Mo2V属于新型耐热不锈钢,主要用于制造临界汽轮机、燃气轮机及航空领域的发电机。我公司接到一批用在临界汽轮机的叶轮锻件,技术条件要求较高,主要体现在材料化学成分及性能指标上。第一次生产此种材质的叶轮,通过对锻造、热处理等关键工序的控制,总结出了一套合理、完整的制造工艺,对后续能够再次承接此类材质的锻件,提供了工艺制定依据及经验。
1Cr12Ni3Mo2V is a new type of heat-resistant stainless steel, mainly used in the manufacture of critical steam turbine, gas turbine and aviation field generator. I received a number of companies used in the critical turbine impeller forgings, higher technical requirements, mainly reflected in the chemical composition and performance indicators. The first production of such material impeller, through the forging, heat treatment and other key processes of control, summed up a set of reasonable and complete manufacturing process, follow-up to be able to undertake such materials forgings, to provide a basis for the development of technology and experience.
