摘要本文介绍了中材装备集团热工分公司为了提升C3旋风筒内筒挂片的使用性能，研究并应用了一种无镍的氮化物和碳化物共同强化奥氏体耐热钢(TRG-ZA-8)，通过添加非金属元素N来形成高强度高硬度高熔点的氮化物，从而保证材质的高温力学性能。试验研究表明，该合金在700℃的拉伸性能优于ZG40Cr28Ni6RE(TRG-ZA-6)，且宏观塑性变形能力优良，能够满足C3旋风筒内筒挂片的使用要求，合金中不含有贵金属元素Ni，实现了较好的经济效益。

Abstract: The article introduced the research of the austenitic heat-resistance steel (TRG-ZA-8) which was from Sinoma Technology & Equipment Group Co., Ltd. - Pyrology Subsidiary Company. The alloy (TRG-ZA-8) was austenitic heat-resistance steel which was reinforced by carbide and nitride. Through adding the non-metal element N, the high temperature behavior of material was reinforced because of the high hardness and high melting-point nitride. The application of high-temperature tensile test expressed that the alloy was better than ZG40Cr28Ni6RE (TRG-ZA-6) at 700℃. The macro-deformation of alloy was excellent. The request of service performance for inner core of C3 cyclone was satisfied. The economic benefit of alloy was fine because of non Ni element.

Key words: austenitic heat-resistance steel carbide nitride high-temperature behavior
