Case-hardening steel achieves high surface hardness through a process called carburizing, where the steel is heated in a carbon-rich environment. This causes carbon atoms to diffuse into the surface of the steel, creating a high concentration of carbon. The carbon atoms then form carbides, which are very hard and increase the steel's surface hardness.
Case-hardening steel achieves high surface hardness through a process called carburizing or nitriding, where the steel is heated in the presence of carbon or nitrogen-rich substances. This allows carbon or nitrogen atoms to diffuse into the surface of the steel, creating a hardened outer layer while maintaining a tough and ductile core.
Case-hardening steel achieves high surface hardness through a process called carburizing, where the steel is heated in a carbon-rich environment. The carbon atoms diffuse into the surface of the steel, forming a high-carbon layer, while the core remains relatively low in carbon content. This differential in carbon concentration leads to a hardened surface layer, enhancing the steel's resistance to wear and tear.
