20Cr2Ni4 Alloy Steel Bar
Yield Strength σs (MPa): Ntau dua lossis sib npaug rau 1080
Elongation δ5 (%) : Ntau dua lossis sib npaug rau 10
Tshooj Shrinkage Z feem pua : Ntau dua lossis sib npaug rau 45
Siv rau carburizing thiab quenching thiab tempering structural qhov chaw nrog ntau zog yuav tsum tau. Nws yog feem ntau siv nyob rau hauv kev tsim cov iav nyob rau hauv lub cav thiab kis tau tus mob ntawm me me thiab nruab nrab-qhov loj me tsheb thiab tsheb laij teb. Nws tseem tuaj yeem hloov 12CrNi3 hlau los tsim cov khoom carburized thiab cyanide qhov chaw uas yuav tsum tau ua haujlwm siab, xws li claws thiab claws siv hauv roj av drilling thiab metallurgical qhib-qhov mines. Cone lub cev.
