SS347H|Uns uns uns unricial uncution 1.4961|AISI 347H Cov Khoom Siv Khoom Siv Khoom Tuam Txhab
SS 347H cov khoom siv, cov pa roj carbon ntau, ruaj khov Austenitic Stainless hlau Alloy, yog ib qho kev siv roj carlessly nrog ib tug ntau dua cov pa roj carbon monoxent ({2}}. 04% yam tsawg kawg nkaus). SS347H tuaj yeem tiv taus kub txog li 1600 degree f (871 degree). SS347H muaj cov chaw corrosion muaj zog nyob rau hauv ntau ib puag ncig cov cheeb tsam, suav nrog sulfuric, nitric thiab phosphoric acids. Nws yog qhov kev xaiv saum toj no hauv kev lag luam xws li kev ua yeeb yam, ntau tiam thiab petrochemical.
HT cov yeeb nkab yog cov khoom lag luam zoo tsim nyog thiab cov neeg xa khoom. Peb yog 347h cov ntaub ntawv xa nrog 15+ export kev. Peb tsis tsuas yog muab cov kav dej,AISI 347H khoom siv 1.4961 phaj, cov kab sib chaws, tab sis kuj cov yeeb nkab fittings, flanges, thiab lwm yam tuaj yeem tiv tauj peb yog xav tau cov ntaub ntawv ntxiv thiab cov nqi pub dawb.
