By combining the annealing temperature and holding time, you can achieve the desired hardness!
By performing quenching, the hardness of steel increases and its strength improves, but the degree of hardening varies depending on the carbon content in the steel, the alloying elements present, and the size of the material, which affects the maximum hardness and depth of hardening. The structure of quenched steel is brittle and in a state of internal stress, so re-heating is carried out to adjust hardness, relieve internal stress, and improve toughness. Tempering after quenching is essential and is broadly classified into low-temperature tempering (below 200°C) and high-temperature tempering (above 500°C), with high-temperature tempering referred to as "quenching and tempering treatment." By combining tempering temperature and holding time, the desired hardness can be achieved. 【Features】 ■ Quenching: A treatment where steel is heated and held above a specified temperature, then rapidly cooled with water, oil, etc. to harden. ■ Tempering: A treatment where the steel is re-heated to a specified temperature after quenching. ■ The combination of tempering temperature and holding time allows for the achievement of the desired hardness. ■ JIS processing symbols: HQ (quenching), HT (tempering) *For more details, please refer to the PDF document or feel free to contact us.
