904L Stainless hlau yeeb nkab Properties
l Kev tiv thaiv zoo heev rau kev ntxhov siab corrosion tawg vim muaj cov ntsiab lus siab nickel.
l Pitting thiab crevice corrosion, intergranular corrosion kuj.
l Qib 904L tsis tshua muaj zog rau nitric acid.
l Zoo heev formability, toughness thiab weldability, vim tsis tshua muaj carbon muaj pes tsawg leeg, nws muaj peev xwm yuav welded siv txhua tus qauv, 904L tsis tuaj yeem hardened los ntawm kev kho cua sov.
l Tsis-sib nqus, 904L yog Austenitic stainless hlau, yog li 904L muaj cov qauv Austenitic.
l Thaum tshav kub kub Resistance, Qib 904L stainless hlau muaj oxidation zoo. Txawm li cas los xij, cov qauv kev ruaj ntseg ntawm qib no poob ntawm qhov kub thiab txias, tshwj xeeb tshaj yog siab dua 400 ° C.
l Kev kho cua sov, Qib 904L stainless hlau tuaj yeem kho cov cua sov ntawm 1090 txog 1175 ° C, tom qab txias txias. Kev kho cua sov yog tsim rau hardening cov qib no.
904L Stainless Hlau Daim Ntawv Thov
l Petroleum thiab petrochemical khoom, piv txwv li: Reactor
