17-4PH Khoom Khoom

17-4PH yog chromium-nickel-copper nag lossis daus hardening martensitic stainless hlau.Qib no ntawm stainless hlau muaj zog xws li siab zog, hardness thiab corrosion kuj.Tom qab kev kho cua sov, cov khoom siv hluav taws xob zoo tag nrho, thiab lub zog compressive tuaj yeem ncav cuag siab li 1100-1300MPa (160-190ksi).Cov qib no tsis tuaj yeem siv qhov kub siab tshaj 300 ° C (572 ° F) lossis qis heev.Nws muaj qhov zoo corrosion kuj rau atmospheric thiab dilute acids los yog ntsev.Nws corrosion kuj yog piv rau 304. Sib nqus.
