Raws li cov hlau tsis huv thiab kub-resistant, 304 steel yeeb nkab yog cov khoom siv dav tshaj plaws rau cov khoom noj, cov khoom siv tshuaj lom neeg thiab kev lag luam atomic zog.
304 steel yeeb nkab yog ib hom universal stainless hlau yeeb nkab, uas yog dav siv los ua cov cuab yeej thiab cov khoom uas xav tau kev ua haujlwm zoo (corrosion resistance and formability).
304 steel yeeb nkab muaj xeb zoo heev thiab corrosion kuj thiab zoo intergranular corrosion kuj.
304 steel yeeb nkab khoom muaj zog corrosion kuj nyob rau hauv nitric acid hauv qab kub kub nrog concentration≤65%.Nws kuj muaj qhov zoo corrosion kuj rau alkali tov thiab feem ntau cov organic thiab inorganic acids.Ib hom hlau alloy siab uas tuaj yeem tiv taus corrosion hauv huab cua lossis hauv cov tshuaj corrosion nruab nrab.Stainless hlau yog ib hom hlau uas muaj qhov zoo nkauj thiab zoo corrosion kuj.Nws tsis tas yuav tau txais kev kho deg xws li xim plating, tab sis muab kev ua si tag nrho rau lub hauv paus ntawm cov khoom ntawm stainless hlau.Nws yog siv ntau yam ntawm cov hlau, feem ntau hu ua stainless hlau.High alloy steels xws li 13 chromium steel thiab 18-8 chromium-nickel steel yog cov sawv cev ntawm cov khoom.
Raws li cov hlau tsis huv thiab kub-resistant, 304 steel yeeb nkab yog cov khoom siv dav tshaj plaws rau cov khoom noj, cov khoom siv tshuaj lom neeg thiab kev lag luam atomic zog.
