304L Cov Yeeb Nkab Hlau Stainless
304L cov yeeb nkab tsis xeb - S30403 (American AISI, ASTM) 304L sib raug rau qib Suav 00Cr19Ni10.
304L stainless hlau, tseem hu ua ultra-low carbon stainless hlau, yog cov khoom siv stainless hlau uas siv tau ntau yam thiab siv dav hauv kev tsim cov khoom siv thiab cov khoom siv uas xav tau kev ua haujlwm zoo (kev tiv taus corrosion thiab formability). Cov pa roj carbon tsawg dua txo cov carbides nag hauv thaj chaw kub ze ntawm qhov vuam, thiab cov carbides nag yuav ua rau intergranular corrosion (welding erosion) ntawm stainless hlau hauv qee qhov chaw.
Nyob rau hauv ib txwm muaj xwm txheej, qhov kev tiv thaiv corrosion ntawm 304L stainless hlau yeeb nkab zoo ib yam li 304 hlau, tab sis tom qab vuam lossis kev ntxhov siab, nws qhov kev tiv thaiv rau intergranular corrosion zoo heev. Yog tsis muaj kev kho cua sov, nws kuj tseem tuaj yeem tswj tau qhov kev tiv thaiv corrosion zoo thiab feem ntau siv hauv qab 400 degrees (tsis yog magnetic, ua haujlwm kub -196 degrees Celsius txog 800 degrees Celsius).
304L stainless hlau yog siv rau hauv cov tshuab sab nraum zoov, cov ntaub ntawv tsim kho, cov khoom tiv taus cua sov thiab cov khoom uas muaj kev kho cua sov nyuaj hauv cov tshuaj lom neeg, thee thiab roj lag luam nrog cov kev xav tau siab rau kev tiv taus intergranular corrosion.
