SQM offers precision-controlled case hardening for alloy and carbon steel components requiring high surface hardness with a tough, ductile core. We provide carburizing and carbonitriding treatments in both batch and continuous furnaces, supporting case depths from 0.2 mm to 2.0 mm and surface hardness up to 64 HRC. Our process ensures minimal distortion and consistent layer uniformity, making it suitable for tight-tolerance parts. Post-hardening operations include quenching, tempering, and optional machining or grinding to meet final dimensional specifications.
Every batch is verified through microhardness profiles, case depth measurement, and metallographic inspection under ISO 9001 and IATF 16949 standards. This service is ideal for high-performance gears, shafts, cams, and other critical components exposed to wear and dynamic loads.
