Application Summary AI generated
GB/T 37558-2019 specifies the post-forging heat treatment processes for heavy steel forgings, including heating parameters, cooling methods, and stress-relief procedures. It is applied in heavy machinery manufacturing, such as for large shafts, rotors, and pressure vessel components, to eliminate forging stresses, refine grain structure, and ensure uniform mechanical properties. This standard is used by foundries and heat treatment facilities to guarantee the quality and reliability of oversized steel parts before final machining.
