Perawatan panas Related
- Anil baja struktural 20CrNiMo Alloy
Alon-alon digawe panas kanggo 850 ℃ lan ngidini kaping cukup, supaya baja dadi sak tenane digawe panas, Banjur kelangan alon ing pawon. Baja paduan 20CrNiMo bakal entuk MAX 250 HB (kekerasan Brinell).
- Pengerasan baja struktural 20CrNiMo Alloy
Dipanasake alon-alon nganti 880-920 ° C, banjur sawise rendhem cukup ing suhu iki quench ing lenga. Temper nalika piranti tekan suhu kamar.
