Tiag Yuav tsis xeb Stainless hlau Welded cov yeeb nkab

Stainless hlau welded yeeb nkab yuav tsis rusting, vim hais tias nws muaj chromium. Feem ntau cov chromium cov ntsiab lus yuav tsum tau raws li 13 ~ 25% (ceeb thawj piv), hloov qhov teeb meem ntawm steel nto oxidation. Yog hais tias peb cia li txiav ib daim ntawm stainless steel phaj nyob rau hauv cov dej, tsawg tshaj li ib ob nto yuav tam sim ntawd tsim ib tug txheej ntawm chromium oxide, lub oxide txheej tej zaum yuav txo tus oxidation tus nqi ntawm yam tsawg kawg kaum txhiab lub sij hawm ntau hlau thiab hlau, nrog rau tus nqi muab xam, mus xeb ib centimeter tuab steel phaj yuav tsum muaj tsawg kawg yog ib lab lub xyoo.
Tab sis stainless steel welded yeeb nkab yog tsis yeej yuav tsis xeb, yog siv ib tug tshuab kuaj kab mob, qhov chaw uas nws ua tau muaj ib tug ntau me me xeb. Saib dua kom zoo, cov me ntsis muaj leej faj, thiab muaj cov elemental leej faj yog inevitable nyob rau hauv tus txheej txheem ntawm siv thiab ua cov hlau. Thaum lub stainless steel raug rau saum huab cua teeb meem no yog zoo, tab sis ib zaug nyob rau hauv dej yuav sai sai no yuav rusty. Thaum no tus taw tes koj yuav tuaj koom nrog txoj lw cov nqi ntawm cov molybdenum, cia li zoo li stainless steel nqi yog ntau dua.
Stainless hlau welded yeeb nkab muaj tej qhov cim tseg manganese sulfide pib xeb, tab sis yuav ua li cas ua lawv pib li cas?
Ib tug tsis ntev los no kev tshawb pom hais tias tus thawj tsis yog tej yam raws li cov leej faj atoms rau hauv sulfuric acid nyob rau hauv dej ua rau xeb, tab sis nyob rau hauv tus txheej txheem ntawm stainless steel manufacturing, cua txias, lub chromium steel txav mus rau tej qhov chaw, tej hloov ntawm manganese nyob rau hauv manganese sulfide , thiab chromium cov ntsiab lus qis nyob ze muaj. Thiab thaum cov ntsiab lus ntawm chromium yog qis tshaj li 13%, cov stainless steel welded yeeb nkab yuav tsum tau xeb.
