1.2379 is a high-carbon, high-chromium cold-work tool steel widely used where wear resistance and dimensional stability are critical. Typical applications include stamping dies, cutting tools, forming tools, and other components with complex geometries that must retain hardness and accuracy after heat treatment.
1.2379 steel hex bolts after vacuum oil quenching treatmentBecause of its alloy composition, 1.2379 is highly sensitive to heat treatment parameters. Conventional processes often struggle with distortion control, surface oxidation, and inconsistent hardness. Vacuum oil quenching addresses these risks by combining a controlled low-oxygen environment with stable heating and rapid, uniform quenching.
