Hardening and Tempering is a thermal process that strengthens steel through a controlled heating and cooling process Hardened and tempered steel strip, is used in many applications including saws, cutting tools as well as springs.
This process will result in improved mechanical properties and give a tougher more durable product. The hardening process involves heating the steel to above the critical transformation temperature for the given grade and then rapidly cooling. Whilst this process achieves the highest mechanical strengths and hardness's, steel in this condition is extremely brittle and therefore requires further treatment in the form of tempering. This consists of reheating the steel to a lower temperature and holding the steel at the given temperature for a given period of time. As with traditional annealing (used to soften steels) this process is conducted in an inert atmosphere to avoid oxidation.
We are able to supply high carbon steels up to 1.10% with a thickness range of 0.20mm to 2mm up to 250mm wide, to customer specified hardness ranges.
