ActiveCorrosion of metals and alloys—Corrosion test for intergranular corrosion susceptibility of low-Cr ferritic stainless steels
金属和合金的腐蚀 低铬铁素体不锈钢晶间腐蚀试验方法
Application Summary AI generated
This standard specifies a test method for evaluating the intergranular corrosion susceptibility of low-chromium ferritic stainless steels. It is applied in metallurgical quality control and material selection for industries such as automotive exhaust systems, kitchen equipment, and construction, where these steels are used in mildly corrosive environments. The test helps ensure long-term durability by detecting sensitization that could lead to grain boundary attack during service.
