Dab tsi yog qhov txawv ntawm 410 thiab 420 stainless hlau?

Dab tsi yog qhov txawv ntawm 410 thiab 420 stainless hlau? Raws li ob hom stainless hlau nrov hauv khw, niaj hnub no, peb txheeb xyuas qhov sib txawv ntawm 410 thiab 420 stainless hlau los ntawm peb yam.

Ob leeg 410 thiab 420 stainless hlau yog martensitic stainless hlau nrog siab zog thiab hardness, tab sis muaj qee qhov sib txawv ntawm kev ua haujlwm thiab kev siv.
Ua ntej ntawm tag nrho cov, los ntawm cov tshuaj muaj pes tsawg leeg taw tes ntawm view, 410 stainless hlau mas muaj 12% mus rau 14% chromium thiab ib tug kuj muaj cov ntsiab lus carbon. Cov ntsiab lus chromium ntawm 420 stainless hlau kuj yog nyob ib ncig ntawm 12% mus rau 14%, tab sis cov ntsiab lus carbon yog siab dua, thiab nws kuj muaj me me ntawm molybdenum, vanadium thiab lwm yam khoom.

Nyob rau hauv cov nqe lus ntawm lub cev muaj zog, vim qhov sib txawv ntawm cov ntsiab lus carbon, 420 stainless hlau muaj ib tug ntau hardness thiab ntau zog tshaj 410 stainless hlau. Qhov no ua rau 420 stainless hlau zoo dua rau kev tsim cov cuab yeej uas yuav tsum tau muaj zog hardness thiab siab zog, xws li scalpels, txiab, thiab lwm yam. 410 stainless hlau muaj kuj zoo toughness thiab yuav siv tau los tsim ib co mechanical qhov chaw uas muaj feem cuam tshuam loads.

Nyob rau hauv cov nqe lus ntawm corrosion kuj, ob leeg muaj tej yam corrosion kuj, tab sis nws yog kuj tsis muaj zog tshaj austenitic stainless hlau. 410 stainless hlau ua tau zoo nyob rau hauv ib puag ncig qhuav, tab sis nws yog ib qho yooj yim rau xeb nyob rau hauv qhov chaw ntub los yog corrosive. 420 stainless hlau muaj me ntsis corrosion kuj zoo dua li 410 stainless hlau vim muaj me me ntawm molybdenum thiab lwm yam khoom.

Tsis tas li ntawd, GNEE tshwj xeeb hauv kev muab stainless hlau daim hlau, stainless hlau kav, stainless hlau coils, stainless hlau foils, stainless hlau profiles, stainless hlau yeeb fittings thiab lwm yam khoom.
