304/304L Stainless hlau yog dab tsi?
• Qib 304 stainless hlau muaj qhov tsawg kawg nkaus ntawm 18% chromium thiab 8% npib tsib xee, ua ke nrog ntau tshaj 0.08% carbon. Cov seem ntawm nws muaj pes tsawg leeg yog tsim los ntawm carbon, manganese, silicon thiab tsawg heev ntawm phosphorous thiab sulfur. Nws txhais tau tias yog Chromium-Nickel austenitic alloy. Qib 304 yog tus qauv "18/8" stainless uas koj yuav zaum pom hauv koj lub lauj kaub thiab cov cuab yeej ua noj. Tsis tas li ntawd, cov hlau yog pliable nyob rau hauv ob qho tib si kub thiab txias ua hauj lwm, tab sis nws teb zoo dua rau txias ua hauj lwm; nws tsuas yog ua haujlwm nyuaj hauv kev ua haujlwm txias. Kev nthuav dav rau qhov kub thiab txias ntawm 800-1500 degree F tuaj yeem ua rau embrittlement thiab yuav tsum tau ua tib zoo saib xyuas.
• Qib 304L yog cov pa roj carbon tsawg ntawm 304, thiab txawm hais tias ob hom muaj ntau yam zoo ib yam, nws yog qhov sib txawv ntawm cov ntsiab lus carbon uas sib txawv. Nws tsis tas yuav tsum tau tom qab-weld annealing kom muaj txiaj ntsig zoo rau kev tiv thaiv corrosion thiab yog li siv dav hauv cov khoom ntsuas hnyav (dhau li 6 hli). Qib 304H nrog nws cov ntsiab lus carbon siab dua pom daim ntawv thov ntawm qhov kub siab. Tsis tas li ntawd, nws kuj muaj qhov ua haujlwm hnyav dua. 304L nthuav tawm kev ua haujlwm zoo hauv ntau qhov chaw thiab qhov kub thiab txias, nrog rau kev xeb thiab oxidation uas tshwm sim dhau sijhawm. Txawm li cas los xij, zoo li ntau cov hlau tsis muaj steel, nws muaj peev xwm ua rau sov chlorine ib puag ncig thiab tuaj yeem ua rau lub qhov dej thiab tawg.
