工程中经常对不锈耐酸钢材和设备按照标准试验方法进行晶间腐蚀倾向的检验。晶间腐蚀倾向试验方法标准主要只对试验方法本身作出详细规定,至于如何应用,在标准(尤其是我国的晶间腐蚀倾向试验方法标准)和其他技术文件中却很少提及。本文根据国内外的有关工作和资料,探讨了这个问题,希望能对不锈耐酸钢晶间腐蚀倾向检验标准的正确应用起到有益的作用。 Often in stainless steel acid plant and equipment in accordance with standard test methods for intergranular corrosion test. Intergranular corrosion tendency test method standard mainly only the test method itself to make detailed provisions, as for how to apply in the standard (especially China’s intergranular corrosion propensity test method standard) and other technical documents rarely mentioned. In this paper, based on the relevant work and information at home and abroad to explore this issue, hoping to correct the corrosion resistance of stainless steel acid corrosion testing standards play a positive role.
