420 xaashi bir ah

Alloy 420 waa bir adag oo adag, martensitic ahama taas oo ah wax ka beddelka Alloy 410. Si la mid ah 410, waxa uu ka kooban yahay ugu yaraan 12% chromium, kaliya ku filan in la siiyo guryaha u adkaysta daxalka. Alloy 420 waxa uu leeyahay kaarboon ka sarreeya Alloy 410 kaas oo loogu talagalay in lagu wanaajiyo xoogga iyo sifooyinka adag. Waxay leedahay ductility wanaagsan xaalad la tirtiray laakiin waxay awood u leedahay in la adkeeyo ilaa Rockwell engegnaanta 50 HRC, engegan ugu sarreeya ee 12% darajooyinka chromium. Sababo la xiriira guryaha adag, Alloy 420 inta badan ma alxan, in kastoo ay suurtogal tahay. Biraha bilaa birta ah ee Martensitic waxaa loogu talagalay adayga sare iyo mararka qaar guryaha kale ilaa xad waa la dhimaa. Iska caabbinta daxalka way ka hooseeyaan darajooyinka austenitic-ka caadiga ah oo kala duwanaanshahooda hawleed ee waxtarka leh ayaa xaddidan lumintooda ductility heerkulka eber-hoosaadka iyo luminta awoodda heerkulka sare ee heerkulka. Iska caabbinta daxalka ugu fiican waxa la gaaraa marka birta la adkeeyo oo dhulka korkiisa la sifeeyo.
