420J1 420J2 alagbara, irin rinhoho
Apejuwe kukuru:
420J1 ati 420J2 irin alagbara, irin awọn ila ni o wa meji wọpọ orisi ti alagbara, irin ohun elo ti o jẹ ti martensitic alagbara, irin jara. Wọn ni diẹ ninu awọn iyatọ ninu akopọ kemikali ati awọn abuda. Eyi ni atokọ kukuru ti ọkọọkan:
1. 420J1 irin alagbara irin rinhoho: 420J1 jẹ irin alagbara irin-kekere erogba pẹlu lile lile ati agbara. Apapọ kemikali rẹ ni igbagbogbo pẹlu ni ayika 0.16-0.25% erogba, nipa 1% chromium, ati awọn oye kekere ti molybdenum. 420J1 nfunni ni idena ipata ti o dara, iṣẹ gige, ati awọn ohun-ini lilọ. O jẹ lilo nigbagbogbo fun ṣiṣe awọn ọbẹ, awọn ohun elo iṣẹ abẹ, awọn ẹya ẹrọ, ati diẹ ninu awọn ohun elo sooro.
2. 420J2 alagbara, irin rinhoho: 420J2 ni a alabọde-erogba alagbara, irin pẹlu ga líle ati wọ resistance. Apapọ kemikali rẹ nigbagbogbo ni ni ayika 0.26-0.35% erogba ati nipa 1% chromium. 420J2 ni akoonu erogba ti o ga julọ ni akawe si 420J1, ti o mu ki lile lile ati iṣẹ gige. Nigbagbogbo a lo fun awọn ọbẹ iṣelọpọ, awọn abẹfẹlẹ, awọn ohun elo iṣẹ abẹ, awọn orisun omi, ati diẹ ninu awọn ẹya ẹrọ.
