Scope

This Standard specifies the technical requirements and corresponding
inspection methods for metallographic examination of induction hardened steel
parts.
This Standard is applicable to the examination of mechanical parts made of
medium carbon structural steel and medium carbon alloy steel with
metallographic structure and effective hardened layer depth after high and
medium induction hardening.
