Taw qhia rau
304 steel yog cov hlau tsis muaj steel ntau, tseem hu ua 18/8 stainless hlau hauv kev lag luam.Nws cov corrosion kuj zoo dua 430 stainless hlau, tab sis tus nqi pheej yig dua 316 stainless hlau, yog li nws yog dav siv nyob rau hauv lub neej, xws li: ib co high-qib stainless hlau tableware, sab nraum zoov stainless hlau railings, thiab lwm yam. Txawm hais tias 304 steel yog. Feem ntau nyob rau hauv Suav teb, lub npe "304 steel" los ntawm Tebchaws Meskas.Ntau tus neeg xav tias 304 steel yog lub npe qauv hauv Nyij Pooj, tab sis hais ncaj qha, lub npe ntawm 304 steel hauv Nyiv yog "SUS304".304 steel yog ib hom universal stainless hlau, uas yog dav siv nyob rau hauv zus tau tej cov khoom thiab qhov chaw uas yuav tsum tau muaj kev kawm zoo (corrosion kuj thiab formability).Txhawm rau kom muaj kev tiv thaiv corrosion nyob rau hauv stainless hlau, cov hlau yuav tsum muaj ntau dua 16% chromium thiab ntau dua 8% cov ntsiab lus nickel.304 stainless hlau yog ib hom ntawm stainless hlau ua raws li American ASTM tus qauv.304 yog sib npaug rau 0Cr18Ni9 stainless hlau hauv peb lub tebchaws.
Tshuaj muaj pes tsawg leeg
Cov tshuaj qib 304 steel yog 06Cr19Ni10 (qib qub -0Cr18Ni9) muaj 19% chromium thiab 8-10% npib tsib xee.

Txheem ntawm
Rau 304 steel yog ib qho tseem ceeb heev, ncaj qha txiav txim siab nws corrosion kuj, tab sis kuj txiav txim siab nws tus nqi.Cov ntsiab lus tseem ceeb tshaj plaws hauv 304 steel yog Ni thiab Cr, tab sis tsis txwv rau ob lub ntsiab lus no.Cov kev cai tshwj xeeb yog teev los ntawm cov qauv khoom.Qhov kev txiav txim siab ntawm kev lag luam ntseeg tias ntev npaum li cov ntsiab lus Ni ntau dua 8%, Cr cov ntsiab lus siab dua 18%, nws tuaj yeem suav tias yog 304 steel.Qhov no yog vim li cas kev lag luam hu ua hom stainless hlau 18/8 stainless hlau.Qhov tseeb, cov qauv khoom tsim nyog rau 304 steel muaj cov kev qhia meej heev, thiab cov qauv khoom no rau cov duab sib txawv ntawm cov hlau tsis muaj steel thiab muaj qee qhov sib txawv.
