After heating and holding at 800℃ (transformation point) or higher, cool down! Mechanical properties such as toughness will be improved.
"Yaki Narashi" refers to a treatment in which steel is heated and held at a specified temperature or higher, followed by air cooling. Forged, cast, and rolled steel materials exhibit coarse crystallization and uneven structures, resulting in inadequate mechanical properties. By heating and holding the steel above 800°C (the transformation point) and then air cooling, the mechanical properties are improved through grain refinement, structural uniformity, enhanced toughness, and the removal of residual stress (stress generated from processing or heat). 【Features】 ■ Treatment involving heating and holding steel at a specified temperature or higher, followed by air cooling ■ Grain refinement and structural uniformity ■ Improved toughness and removal of residual stress (stress generated from processing or heat) ■ Enhanced mechanical properties ■ JIS processing symbol: HNR *For more details, please refer to the PDF document or feel free to contact us.
