Application Summary AI generated
This standard specifies the technical requirements, process control methods, and quality inspection criteria for carburizing, carbonitriding, quenching, and tempering of steel parts. It is applied in the manufacturing and heat treatment industries, particularly for automotive, machinery, and tooling components that require enhanced surface hardness, wear resistance, and fatigue strength. The standard is used by heat treatment facilities and quality assurance teams to ensure consistent and reliable case-hardening results for load-bearing steel parts.
