Scope

This Standard specifies the grades, chemical composition, chemical
composition deviation of finished products, mechanical properties, and
sampling locations of mechanical properties, etc. of structural steel for forgings.
This Standard applies to general forgings for sampling determination of
mechanical properties after integral heat treatment in metallurgical, mining,
shipping, engineering machinery and other equipment.
The mechanical properties of this Standard do not apply to forgings such as
main shafts, rotors, impellers, and pressure vessels rotating at high
temperature and high speed in power station equipment.
