Carburizing Bearing Steel

we provide Carburizing Bearing Steel, an advanced material designed for applications requiring high surface hardness and a tough, ductile core. This specialized steel offers excellent fatigue resistance and durability, making it ideal for demanding industrial, automotive, and aerospace applications. Carburizing Bearing Steel is a low-carbon alloy steel designed for case-hardening processes like carburizing or carbonitriding. This process increases the carbon content at the surface, resulting in a hard, wear-resistant outer layer while maintaining a tough and flexible core. The carburized surface provides exceptional resistance to wear and deformation. The low-carbon core ensures ductility and toughness, allowing it to absorb impacts and stresses without cracking. Carburizing depth and hardness can be tailored based on application requirements.
