This standard specifies the corrosion mass loss of urea grade ultra-low carbon chromium nickel molybdenum austenitic stainless steel in 65% boiling nitric acid solution as a test method for inspection of intergranular corrosion tendency. It is suitable for evaluating the influence of heat treatment and welding process on the corrosion resistance performance of materials, and testing the corrosion resistance performance of welds. The standard provides an important inspection basis for the intergranular corrosion resistance of materials in the manufacturing process of related equipment to ensure the long-term reliability and safety of equipment.
