GB/T 13305-2008
AbolishedMicrographic method for determining area content of the α-phases in stainless steels
不锈钢中α－相面积含量金相测定法
Application Summary AI generated
This standard specifies a metallographic testing method to determine the area fraction of α-phase (ferrite) in stainless steel microstructures. It is applied in quality control and material analysis for stainless steel producers, manufacturers, and testing laboratories to verify phase balance, which influences corrosion resistance and mechanical properties. The method is particularly relevant for evaluating duplex stainless steels and other grades where α-phase content must be controlled during production or acceptance testing.
