IHT Wire

Induction-hardened and tempered wire is a type of steel wire that has undergone a specialized heat treatment process known as induction hardening and tempering. Induction hardening is a heat treatment process where a localized area of a metal component, in this case, the wire, is rapidly heated using high-frequency alternating current (induction heating). Once the desired temperature is reached, the heated portion is quenched by cooling it rapidly, typically using a water-based quenching medium. This process results in the formation of a hardened surface layer on the wire, increasing its wear resistance and hardness.

After induction hardening, the wire is often tempered to improve its toughness and reduce the risk of brittleness. Tempering involves reheating the hardened wire to a lower temperature and holding it there for a specified period before allowing it to cool naturally. This process helps to relieve internal stresses and refine the microstructure of the wire, enhancing its toughness while maintaining sufficient hardness.
