弹性合金用于石油化工仪表或其它具有一定腐蚀性酸溶液内的弹性器件越来越广泛。国外对于弹性合金的腐蚀性能研究甚少。本文较全面地介绍了几种典型弹性合金在常用酸溶液中的腐蚀性能试验结果。本研究对合理选用弹性材料具有一定的参考价值。试验所选择的弹性合金牌号具有一定的实用代表性。如: Fe-Ni-Co基型合金:MC-200 Fe-Ni-Cr基型:Я1T、A-286、3J1、3J3、3J53、H40X20MTЮБP Ni-Cr基型合金:IN-600、IN-718、INX-750 Ni-Cr-Co基型合金:3J36 试验的介质是:HF(15％、30％)、HCl(15％、30％)、HNO_3(30％、50％)、H_2SO_4(15％、50％)、
Elastic alloys used in petrochemical instruments or other corrosive acid solution has a more and more flexible devices. Abroad for the corrosion properties of elastic alloys little research. This article introduces the corrosion test results of several typical elastic alloys in common acid solution. This study has a certain reference value for the rational selection of elastic materials. The test selected elastic alloy grades have a certain practical representation. Such as: Fe-Ni-Co base type alloy: MC-200 Fe-Ni-Cr base type: Я1T, A-286,3J1,3J3,3J53, H40X20MTЮБP Ni-Cr base type alloy: IN-600, IN-718, The medium of INX-750 Ni-Cr-Co base alloy: 3J36 is HF (15%, 30%), HCl 50%),
