Khoom Taw qhia

Khoom Description

SAE8620H steel sib npaug rau 20CrNiMoH hauv Suav teb. Nws cov qauv kev ua tau zoo yog ASTM A29 / A29M-04. 8620H steel bar yog dav siv hauv carburizing thiab carbon-nitriding txheej txheem. Tom qab carburizing, qhov saum npoo ntawm SAE8620H nthuav tawm siab tawv, hnav tsis kam, thiab tiv taus lub zog qaug zog. Nws lub plawv tseem khaws cov ductility zoo, ua rau nws muaj peev xwm tiv taus qhov hnyav hnyav. ASTM8620H feem ntau yog siv los ua cov khoom siv rau kev poob siab thiab hnav-tiv taus qhov chaw xws li tsheb bearings ect.
