This standard specifies the selective corrosion depth and microstructure inspection method of urea-grade ultra-low carbon chromium nickel molybdenum austenitic stainless steel, which is suitable for selective corrosion and metallographic inspection after intergranular corrosion test. The standard describes in detail the selection and fabrication requirements of the sample, provides guidance for checking the corrosion point and microstructure changes, and provides an effective means for detecting the manufacturing mass of urea high voltage equipment to ensure the reliability and safety of the equipment in use.
