本文介绍了一种耐腐蚀、耐高温、无磁高弹性合金Ni40Cr20Co20Mo。该合金具有优良的耐蚀性能,弹性高、强度大,所制成的高温扭管,是高温调节仪表的关键元件,在500℃高温下综合性能良好,完全满足在较复杂的工作环境下(高温、高压、腐蚀介质)测量仪表用弹性敏感元件的要求。本合金系奥氏体型合金。试样采用真空感应加电渣重熔的冶炼工艺,钢锭经锻造,热轧或冷拉成管或带料。尽管本合金强度高、硬度大,但在淬火状态下塑性提高,因而亦可制成形状复杂的弹性元件。合金
This article describes a corrosion-resistant, high temperature, non-magnetic high-elastic alloy Ni40Cr20Co20Mo. The alloy has excellent corrosion resistance, high elasticity, high strength, made of high temperature torsion tube, is a key component of high temperature regulation instrument, good overall performance at 500 ℃ high temperature, fully meet the more complex work environment High temperature, high pressure, corrosive media) Requirements for elastic sensing elements used in measuring instruments. This alloy is austenitic alloy. Sample using vacuum induction plus ESR smelting process, ingot forging, hot rolled or cold drawn into the tube or strip. Although this alloy has high strength and high hardness, its plasticity increases when quenched, so that it can also be made into a complicated elastic element. alloy
