High Carbon Steel with Hardened and Tempered
Hardening and Tempering is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the critical transformation temperature for the given grade and then rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated 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.
H+T steel strips are widely used for rolling shutter door springs, band saw blade, scraper, trowel, putty knives, shoe insole, knives, kinds of flat springs etc, which don`t require severe bending.
