Carburizing
Carburizing is a thermochemical heat treatment process that increases the carbon content near the surface of suitable steel components. When followed by controlled hardening, it produces a wear-resistant outer layer while maintaining a comparatively tougher core, making it valuable for gears, shafts, and transmission parts.

Manufacturing overview
Carburizing introduces carbon into the surface of low-carbon or suitable alloy steels at elevated temperatures.
After carbon diffusion, components are typically hardened and tempered to achieve the required surface and core properties.
Common carburizing methods include gas carburizing, low-pressure carburizing, and other controlled-atmosphere processes.
Typical applications include gears, pinions, transmission shafts, bearing components, and heavily loaded mechanical parts.
Common materials include 16MnCr5, 20MnCr5, 8620, and selected nickel-chromium-molybdenum steels.
Critical requirements include effective case depth, surface hardness, core hardness, retained austenite limits where specified, and dimensional stability.
Carburizing may introduce distortion during subsequent quenching, requiring suitable machining allowances and finishing operations.
Buyers should specify material grade, component geometry, required case depth, hardness values, critical tolerances, quantity, and inspection requirements.
Quality verification may include hardness traverses, case depth measurement, microstructural examination, distortion checks, and material traceability.
