After heating and holding at 800℃ (transformation point) or higher, cool down! Mechanical properties such as toughness are 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, or rolled steel materials exhibit coarse crystallization and uneven structures, resulting in inadequate mechanical properties. By heating and holding at temperatures above 800°C (the transformation point) and then air cooling, the crystallization is refined, the structure is homogenized, toughness is improved, and residual stresses (stresses generated from processing or heat) are eliminated, thereby enhancing mechanical properties. [Features] - Treatment involving heating and holding steel at a specified temperature or higher, followed by air cooling - Refinement of crystallization and homogenization of structure - Improvement of toughness and elimination of residual stresses (stresses generated from processing or heat) - Enhancement of mechanical properties - JIS processing symbol: HNR *For more details, please refer to the PDF document or feel free to contact us.
