304 304L Stainless Hlau Tube
Raws li cov hlau tsis muaj cua sov-resistant, 304 steel yeeb nkab yog cov khoom siv dav siv hauv cov khoom noj khoom haus, cov khoom siv tshuaj lom neeg, thiab cov khoom siv hluav taws xob atomic.
Dab tsi yog qhov txawv ntawm stainless hlau 304, 304H thiab 304L?
Stainless hlau yeeb nkab 304 yog hom 18-8 austenitic stainless hlau muaj kwv yees li 18% chromium thiab 8% npib tsib xee. Tsis tas li ntawd, nws muaj cov khoom me me xws li carbon, manganese, silicon thiab phosphorus. 304 stainless hlau yeeb nkab muaj qhov zoo corrosion kuj thiab vuam zog thiab tsim nyog rau kev siv lub hom phiaj dav dav.
Stainless hlau 304H yeeb nkabyog ib tug high-carbon version ntawm stainless 304 steel yeeb nkab, uas muaj ib tug ntau dua carbon cov ntsiab lus, feem ntau ntawm 0.04% thiab 0.1%. Cov ntsiab lus carbon siab ua rau 304H steel kav muaj qhov zoo dua qhov kub thiab txias tsis kam, ua rau lawv tsim nyog rau kev siv hauv qhov chaw kub, xws li qhov cub, qhov cub thiab cov kav dej kub.
304L steel yeeb nkab yog ib qho qis-carbon version ntawm stainless hlau 304, nrog nws cov ntsiab lus carbon tswj hauv qab 0.03%. Cov ntsiab lus ntawm cov pa roj carbon tsawg pab txhim kho qhov sib txawv ntawm cov corrosion kuj ntawm 304L, ua rau nws haum rau cov qauv welded thiab kev siv hauv qee qhov chaw tshwj xeeb, xws li kev lag luam tshuaj thiab khoom siv kho mob.
Vim muaj cov ntsiab lus carbon siab, stainless hlau 304H steel yeeb nkab tau zoo dua oxidation tsis kam thiab kub siab zog nyob rau hauv qhov kub thiab txias. Hauv kev sib piv, kev ua tau zoo ntawm 304 thiab 304L alloy steel kav yog txo me ntsis hauv qhov kub thiab txias.
Stainless hlau 304 muaj kev tiv thaiv corrosion zoo thiab tuaj yeem tiv thaiv kev yaig ntawm cov xov xwm corrosive, xws li dej, feem ntau cov organic acids thiab inorganic acids.
Vim yog qhov sib ntxiv ntawm cov ntsiab lus siab carbon, 304H stainless hlau kav muaj qhov zoo dua corrosion kuj nyob rau hauv qhov kub thiab txias ib puag ncig thiab tuaj yeem tiv taus qhov yaig ntawm acidic gases thiab kub corrosive media.
Stainless hlau seamless 304L steel yeeb nkab txhim kho nws cov tsis kam mus rau intergranular corrosion los ntawm kev txo cov ntsiab lus carbon. Nws muaj kev tiv thaiv corrosion zoo tiv thaiv corrosive media hauv qee qhov chaw tshwj xeeb, xws li acidic chloride daws thiab dej hiav txwv.
