GB/T 14979-1994
ActiveEutectic carbide of steel--Micrographic method using standard diagrams
钢的共晶碳化物不均匀度评定法
Application Summary AI generated
This standard specifies a micrographic method using standard diagrams for evaluating the degree of eutectic carbide non-uniformity in steel. It is primarily applied in the metallurgical industry for quality inspection of tool steels, high-speed steels, and bearing steels, where carbide distribution directly affects material performance. The method is used during manufacturing and acceptance testing to assess carbide banding and segregation in forged or rolled steel products.
