Pwosesis: Chofe a 900-950 ° C (ostenitizasyon), kenbe, Lè sa a, lè -fre.
Effect: Refines ferrite-pearlite microstructure, eliminates rolling segregation. Improves 0°C impact energy by 25–40% (from 27J to 35–38J), ideal for thick plates (>16mm).
Pwosesis: Nòmalize an premye, apresa rechofe a 550–650 °C, kenbe, epi lè-fre.
Efè: Pli lwen soulaje estrès rezidyèl pandan y ap kenbe amann mikrostruktur. Ranfòse enèji enpak 0 ° C pa 50% (a 40-45J), apwopriye pou estrikti soude.
Pwosesis: Kontwole woule (1100-1200 ° C) + rechofaj a 750-850 ° C.
Efè: Kreye ultra-fè ferit, ogmante enèji enpak 0°C a plis pase 50J. Itilize pou aplikasyon tanperati ki wo-pèfòmans ba-.
Pwosesis: Chofe a 550–600 °C, kenbe, epi ralanti -fre.
Efè: Diminye estrès rezidyèl (kritik pou pati soude/machine) san yo pa chanje mikwostrikti, anpeche estrès -pwovoke ka zo kase frajil.
