Carburizing Heat Treatment for Machined Gears, Parts & Stampings
Welcome to our detailed exploration of the carburizing heat treatment process for machined gears, machined parts, and stampings. This transformative method offers technical benefits, especially for steel components, ensuring they’re primed for high-performance applications.
Technical Benefits of Carburizing:
- Enhanced Surface Hardness: By introducing more carbon into the surface layer of the heat-treated components, the carbon-rich surface transforms into hard martensite. This offers a robust and wear-resistant exterior.
- Tough Core Properties: While the surface is hardened, the core remains relatively ductile, balancing wear resistance and impact absorption.
- Improved Wear & Fatigue Resistance: Carburizing leads to a reduction in wear rates and an enhanced fatigue limit, especially crucial for components like gears under repeated loads.
- Versatility in Component Geometry: It’s adaptable for complex-shaped components, fitting the needs of intricate parts across various industries.
- Reduced Distortion: Ensures components retain desired dimensions post-treatment.
- Selective Carburizing: The use of carb stop-off paints makes selective carburizing case hardening possible, with carburize-only processes also on offer, in addition to blasting and straightening.
