Depending on the needs of specific industries, metal materials can be processed in a lot of ways. One of the processes that can be applied to metal materials is induction hardening.
Induction hardening is the process of hardening the surface of metal materials. During this process, a metal workpiece is typically placed inside a copper coil, which carries a substantial level of alternating current. The alternating current can then generate heat at and near the surface of the workpiece. The temperate of this process often goes above the transformation temperature of the workpiece. After the heating process, the metal workpiece will then be quenched, changing its structure effectively.
Benefits of Induction Hardening
Through the process of induction hardening, metal workpieces are expected to obtain some benefits.
One of the benefits of induction hardening is that it can increase the wear resistance of metal products. With increased wear resistance, metal products are expected to last for a long time, despite using them at various applications. Another benefit of induction hardening is that it can increase the fatigue strength of the materials. The residual compressive stress that is generated by the process allows workpieces to have a hardened structure near their surface, protecting the core from possible damages and issues.
Aside from increased wear resistance and fatigue strength, induction hardening can also grant workpieces the chance to have an adjusted hardness level after conducting the said process. Lowering the hardness of the materials while decreasing their brittleness is possible through tempering.
One more benefit of induction hardening is that it allows industries to utilise low-cost steel materials. These materials are often machinable due to their minimal carbon content. They likewise have a low risk of cracking and other negative effects. These features make the process cheaper compared to others.
Induction Hardening Applications
Given the benefits of induction hardening, it can truly generate excellent products out of various metal materials. It can even be used to enhance the mechanical properties of various ferrous components, making the process very useful for repairing field failures or warranty claims. It can likewise generate a lot of products since it does not require holding time.
Some of the materials that can be used for induction hardening include alloy steel, carbon steel, powder metal, cast iron, and martensitic stainless steel. Some products that can be created out of induction hardening are gears, axles, shafts, cam lobes, stampings, and spindles.
