20CrMnTi iav Steel Bar
Yield Strength (MPA): Ntau dua lossis sib npaug rau 850
Elongation (δ5 / feem pua): Ntau dua lossis sib npaug li 10 feem pua
Txo hauv Cheeb Tsam (ψ / feem pua): Ntau dua lossis sib npaug li 45 feem pua
20CrMnTi yog cov hlau carburized nrog kev ua tau zoo thiab muaj zog hardenability. Tom qab carburizing thiab quenching, nws muaj ib qho nyuaj thiab hnav-resistant nto thiab ib tug tawv chaw, siab low-temperature impact toughness, medium weldability, thiab zoo machinability tom qab normalizing. Nws yog ib qho kev hloov steel ntawm 18CrMnTi, uas yog dav siv los ua carburized qhov chaw. Hauv kev lag luam tsheb thiab tsheb laij teb, nws yog siv los ua ib qho tseem ceeb carburized nrog ib feem ntawm tsawg dua 30 hli, uas tuaj yeem tiv taus kev kub ceev, nruab nrab lossis hnyav, cuam tshuam thiab kev sib txhuam, xws li iav, ncej, iav nplhaib, iav ncej, lub ntsiab ncej ntawm zawv zawg kabmob, crosshead, claw clutch, worm, thiab lwm yam.
