35CrMnSiA yog ib qho tsis tshua muaj hlau alloy ultra-siab lub zog steel, kev kho cua sov nrog zoo tag nrho cov khoom siv, siab zog, txaus toughness, hardenability, weldability (preheat ua ntej vuam), kev ua thiab kev tsim yog zoo dua, tab sis corrosion kuj thiab oxidation kuj yog tsawg, feem ntau yog siv qhov kub thiab txias los yog isothermal quenching.
35CrMnSiA steel phaj siv cov qauv: kev ua raws li GB / T 3077-1999 tus qauv.
35CrMnSiA steel phaj tus me nyuam raws li txoj cai: annealed, normalized, normalized tempering, kuj yuav raug teev raws li cov kev cai ntawm kev xa khoom.
Tshuaj muaj pes tsawg leeg:
