Cov khoom siv hlau ncej thiab lawv cov yam ntxwv

Cov pa roj carbon steel: xws li 35, 45, 50 steel, thiab lwm yam., muaj cov khoom siv dav dav, tshwj xeeb tshaj yog 45 steel yog siv dav tshaj plaws. Nws qhov kev ua tau zoo tuaj yeem ua tau zoo ntxiv los ntawm normalizing lossis quenching thiab tempering kho.
Alloy steel: Nws muaj ntau dua txhua yam khoom, tab sis tus nqi siab dua. Nws yog haum rau shafts nrog tshwj xeeb yuav tsum tau, xws li high-ceev shafts thiab shafts nyob rau hauv high kub, siab ceev thiab hnyav load tej yam kev mob. Feem ntau siv cov hlau alloy xws li 20Cr, 20CrMnTi, 38CrMoAlA, thiab lwm yam.
cam khwb cia hlau: xws li grey cam khwb cia hlau thiab ductile hlau, haum rau lub teeb load, tsawg ceev thiab cuam tshuam load zaus, vim hais tias nws muaj tej yam kev sib txhuam txo thiab hnav tsis kam 4.
