GB/T 40403-2021 "Corrosion of Metals and Alloys, Method for Determining the Resistance to Stress Corrosion Cracking of Metals by Four-point Bending Method" specifies a method for measuring the resistance to stress corrosion cracking performance of metals by using the four-point bending method. The standard covers test principles, sample preparation, instrumentation, test procedures and result evaluation. By applying specific bending stresses and combining with the corrosive environment, the ability of metal materials to resist stress corrosion cracking is scientifically evaluated, providing reliable technical standards for material performance testing and engineering applications.
