304L Stainless Steel Pipe Description
304L stainless hlau yeeb nkab--S30403 (American AISI, ASTM) 304L sib raug rau Suav qib 00Cr19Ni10.
304L stainless hlau, tseem hu ua ultra-low carbon stainless hlau, yog cov khoom siv stainless hlau ntau yam uas tau siv dav hauv kev tsim khoom thiab cov khoom uas xav tau kev ua haujlwm zoo (corrosion resistance and formability). Cov ntsiab lus qis dua txo qis cov nag lossis daus ntawm carbides nyob rau hauv thaj chaw uas muaj kev kub ntxhov nyob ze ntawm qhov vuam, thiab nag lossis daus ntawm carbides yuav ua rau muaj kev cuam tshuam ntawm intergranular corrosion (welding yaig) ntawm stainless hlau hauv qee qhov chaw.
Raws li ib txwm muaj, qhov kev tiv thaiv corrosion ntawm 304L stainless hlau yeeb nkab zoo ib yam li 304 steel, tab sis tom qab vuam los yog kev ntxhov siab, nws tsis kam mus rau intergranular corrosion yog zoo heev. Tsis muaj kev kho cua sov, nws tuaj yeem tswj tau zoo corrosion kuj thiab feem ntau yog siv hauv qab 400 degrees (tsis yog hlau nplaum, kev khiav hauj lwm kub -196 degrees Celsius mus rau 800 degrees Celsius).
304L stainless hlau yog siv nyob rau hauv sab nraum zoov machinery, tsev cov ntaub ntawv, tshav kub-resistant qhov chaw thiab qhov chaw uas nyuaj thaum tshav kub kub kho nyob rau hauv cov tshuaj, thee thiab roj industries nrog siab xav tau kev tiv thaiv intergranular corrosion.
