Hardened & Tempered Steel Strips

Hardened & tempered spring steel strips / coils are also commonly known as "H & T steel strips". Hardening and Tempering is a thermal process that strengthens steel strips through a controlled heating and cooling process. This process of hardening and tempering improves the mechanical properties of the steel strip and gives a tougher and more durable product. The hardening process involves heating the steel strip to above the critical transformation temperature for the given grade and then rapidly cooling. The problem here is that the steel strip in this condition is extremely brittle and therefore requires further treatment in the form of tempering. This consists of reheating the steel strip to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has high degree of toughness and has excellent spring properties. This type of steel strip can be used for various applications like wood cutting saws, industrial knives, sheet metal components, automobile sector and springs. 

The steel strips / coils that are produced during the hardening & tempering process can be cold rolled hardened & tempered low carbon steel strips / coils or cold rolled hardened & tempered medium carbon steel strips / coils or cold rolled hardened & tempered high carbon steel strips / coils.
