Carburizing: Deep Surface Hardening for Wear Resistance and Tough Core

Achieve deep surface hardening with our carburizing service. Enjoy a wear-resistant case and a tough, ductile core for superior component performance.

Introduction
Carburizing is an advanced thermochemical treatment that enriches the surface of steel components with carbon, creating a hard, wear-resistant case while preserving a ductile, tough core. This process is ideal for parts subjected to high contact stresses, delivering extended service life without compromising structural integrity.

Key Benefits

  • Deep Surface Hardening
    Case depths up to 1.5 mm provide exceptional wear resistance in high-stress applications.

  • Tough Core Strength
    The low-stress, high-carbon gradient maintains core ductility and impact resistance.

  • Enhanced Fatigue Life
    Compressive stresses in the hardened layer increase resistance to crack initiation and propagation.

  • Dimensional Accuracy
    Controlled heating and cooling minimize distortion, preserving tight tolerances.

  • Versatile Material Compatibility
    Suitable for a wide range of carbon and low-alloy steels, as well as certain stainless grades.

How It Works

  1. Preparation: Thorough cleaning and masking of non-treatment areas.

  2. Carburizing: Exposure to a carbon-rich atmosphere (gas or pack) at 900–950 °C.

  3. Diffusion: Soak time calibrated to achieve the target case depth.

  4. Quenching: Rapid cooling (oil or gas) to transform the case to martensite.

  5. Tempering: Post-quench temper to relieve stresses and optimize hardness profile.

  6. Inspection: Hardness testing, case-depth measurement, and microstructure verification.

Applications

  • Automotive Parts: Gears, camshafts, flywheels

  • Power Transmission: Shafts, sprockets, coupling hubs

  • Industrial Equipment: Bearings, rollers, pinions

  • Tooling: Worms, racks, cold-forming dies
