17-4PH 630 Stainless Hlau Bar
Lus piav qhia luv luv:
Saky Steel's 17-4PH / 630 / 1.4542 yog ib qho nrov tshaj plaws thiab feem ntau siv stainless chromium-nickel alloy steels nrog tooj liab additive, nag lossis daus hardened nrog martensitic qauv. Nws yog tus cwj pwm los ntawm kev ua haujlwm siab corrosion thaum tswj cov khoom muaj zog, nrog rau hardness. Cov hlau tuaj yeem ua haujlwm nyob rau hauv qhov kub ntawm -29 ℃ to 343 ℃, thaum tuav cov kev ntsuas tsis zoo. Tsis tas li ntawd, cov ntaub ntawv nyob rau hauv qib no yog tus cwj pwm los ntawm qhov zoo ductility thiab lawv cov corrosion kuj yog piv rau 1.4301 / X5CrNi18-10.
17-4PH, tseem hu ua UNS S17400, yog martensitic nag lossis daus-hardening stainless hlau. Nws yog cov khoom siv ntau yam thiab siv dav hauv ntau yam kev lag luam, xws li aerospace, nuclear, petrochemical, thiab kev ua zaub mov.
17-4PH muaj lub zog siab, zoo corrosion kuj, thiab hardness zoo piv rau lwm yam stainless hlau. Nws yog sib xyaw ntawm 17% chromium, 4% npib tsib xee, 4% tooj liab, thiab ib qho me me ntawm molybdenum thiab niobium. Kev sib xyaw ntawm cov ntsiab lus no muab cov hlau nws cov khoom tshwj xeeb.
Zuag qhia tag nrho, 17-4PH yog cov khoom siv ntau yam thiab muaj txiaj ntsig zoo uas muaj qhov sib npaug zoo ntawm cov khoom siv rau ntau yam kev siv.
