ActiveMethods of measurement for ferrite content in austenitic Cr-Ni stainless steel weld metals
铬镍奥氏体不锈钢焊缝铁素体含量测量方法
Application Summary AI generated
This standard specifies the methods for measuring the ferrite content in the weld metal of austenitic chromium-nickel stainless steels. It is applied in the manufacturing and quality control of welded components, particularly in industries such as chemical processing, pressure vessels, and nuclear power, where controlling ferrite levels is critical to prevent hot cracking and ensure corrosion resistance. The standard provides both magnetic and metallographic techniques for precise measurement during welding procedure qualification and production inspection.
