spheroidizing annealing:860 ℃ X 2h furnace cooling sa 750 ℃ at pagkatapos ay furnace cooling sa 500-550 ℃, alisin at paglamig ng hangin
Na-quenched + tempered:1100℃ X 20min step quenching + 700℃ X 1h tempering,alisin at air cooling
Pagsusubo: 1030 ℃ X 40min na pagsusubo ng langis(800 ℃ preheating, vacuum 2.5 pa) Tempering: 250 ℃ X 1h
Ang malamig na trabaho ay namatay na bakal, bakal na hardenability, pagsusubo, at tempering tigas, wear resistance, lakas ay mas mataas kaysa sa Cr12. Ginagamit sa paggawa ng iba't ibang cold stamping dies at mga tool na may malalaking cross-section, kumplikadong hugis at mabibigat na kondisyon sa pagtatrabaho, tulad ng punching die, trimming die, piping dies, deep drawing dies, circular saw, standard tools, at gauge Thread rolling die , atbp.
