AISI SAE 4130 4140 4145H Birta Wareega ee Bar godan
Astaamaha
4130 4135 4140 4145H birta birta ah waa bir daawaha carbon hooseeya.Waxay ka tirsan yihiin Chrome-Molly alloy oo ka kooban chromium iyo molybdenum oo ah wakiilada xoojinta.
4130 bir wareeg ah ayaa leh karti shaqo oo wanaagsan, habacsanaan wax-qabad yar, iyo iska caabin daal aad u fiican.Waxay ka tirsan tahay qaybta birta adag ee dhexdhexaadka ah ilaa sare.Daawaynta kulaylka ka dib, 4140 waxay leedahay awood wanaagsan iyo sifooyin farsamo oo dhamaystiran, karti hab-socod wanaagsan, iyo waxsoosaar sare.Heerkulka adeeggu waa 427 darajo Celsius.
4140 waxa uu leeyahay xoog sare, karti adag, adayg, iyo qallafsanaan inta lagu jiro deminta.Waxay leedahay xoog gurguurta oo sarreeya iyo xoog adkaysi heerkul sare.Waxaa loo isticmaalaa wax soo saarka foornada oo u baahan xoog sare iyo qaybo ka weyn oo la demiyo iyo kuwa dabci ah oo ka badan 4135 birta, sida qalabka waaweyn ee jiid jiidashada, qalabka gudbinta xoojisa, faashashka danbe, ulo isku xidha iyo clips guga oo aad u raran.
