HLQ is a top induction heating machine manufacturer specializing in induction hardening machine,melting furnace,brazing machine,PWHT machine,welding PWHT stress relieving system,etc.
Induction hardening is a surface hardening process that uses electromagnetic induction to heat the surface of a metal object. The object is then cooled rapidly, creating a hardened surface layer while leaving the interior of the object relatively unchanged. This process is commonly used to improve the wear resistance and fatigue life of metal parts, particularly those used in high-stress applications such as gears, bearings, and shafts. Induction hardening is popular due to its speed and precision, as well as its ability to produce consistent results across large batches of parts.
