Hardened & Tempered Steel Strips

Hardened & tempered spring steel strips are also commonly known as "H & T steel strips". Hardening and Tempering is a thermal process that strengthens cold rolled steel strips through a controlled heating and cooling process. This process of hardening and tempering improves the mechanical properties, flatness 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 through quenching. The problem here is that the steel strip in this condition is extremely brittle and has internal strains, 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.

Our Hardened & Tempered spring steel strips are manufactured through the most modern hardening and tempering lines. This assures :

1) Uniform hardness
2) Excellent ductility and Shock Resistance.
3) High degree of toughness and has excellent spring and cutting properties.
4) Perfect workability due to Excellent Flatness and Fine Tempered Martensite     Microstructure Smooth & Uniform Surface Finish.
5) Smooth & uniform surface finish.

Our H&T spring steel strips are used for a large number of applications like valve plate and flapper valve for compressor units, clock spring, clutch assembly, horn diaphragm and bracket, industrial knives, etc.
