It becomes possible to increase tensile strength and improve workability and machinability!
Kyowa Heat Treatment Co., Ltd. specializes in heat treatment of raw materials, primarily forged and cast products. Heat treatment consists of four methods: "quenching and tempering," "annealing," "normalizing," and "stress relieving." [Features] ■ Increases tensile strength ■ Improves machinability and cutting performance *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Heat Treatment Methods】 ■Quenching and Tempering - By tempering, FCD450 can achieve the tensile strength of FCD600. ■Annealing - Graphitizing annealing to decompose the chill structure formed during solidification. - Ferritizing annealing to remove pearlite for hardness reduction. (If pearlite structure remains, the hardness will appear higher.) ■Normalizing - To refine the base structure into a fine pearlite structure, aimed at increasing hardness and strength (refinement of pearlite). ■Stress Relief - To remove internal stresses and distortions that occur during solidification. *For more details, please refer to the PDF document or feel free to contact us.
