ActiveFabrication and inspection method for high pressure urea equipment - Part 3: Intergranular corrosion tendency test for ultra low-carbon chromated nickel molybdenum austenitic stainless steel of urea grade
尿素高压设备制造检验方法 第3部分：尿素级超低碳铬镍钼奥氏体不锈钢晶间腐蚀倾向试验
Application Summary AI generated
This standard specifies the intergranular corrosion tendency test method for ultra low-carbon chromated nickel molybdenum austenitic stainless steel used in high-pressure urea equipment. It is applied during the manufacturing and inspection of urea reactors, strippers, and other critical components in chemical fertilizer plants to ensure material resistance to corrosive urea environments. The test verifies that the steel meets the stringent corrosion performance requirements for long-term service in high-temperature, high-pressure urea synthesis processes.
