Quenching and tempering, annealing, and vacuum hardening are performed to achieve the high hardness and strength of steel!
At Dainec Co., Ltd., we perform "heat treatment processing." Quenching and tempering are conducted to bring out the high hardness and strength of steel. Quenching alone can make it hard but brittle, so tempering is carried out to enhance toughness. We also perform complete annealing to adjust the metal structure and achieve softening, as well as normalizing and solution treatment. 【Features】 ■ Quenching and tempering: Tempering is also performed to enhance toughness. ■ Complete annealing: Achieves adjustment of the metal structure and softening. ■ Stress relief annealing: Removes residual stress. ■ Normalizing: Uniformizes the metal structure, refines grain size, and improves machinability. ■ Solution treatment: Dissolves carbides precipitated in austenitic stainless steel. ■ Oxidation-free quenching: Prevents the adhesion of oxide films to the surface of steel and the loss of surface carbon. *For more details, please refer to the PDF document or feel free to contact us.
