ASTM A312 Qib TP304 / TP304L Hlau Yeeb Nkab Rau Taiwan, Suav

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 cov khoom zoo (corrosion resistance and formability). Ntawm lwm tus, cov ntsiab lus chromium ua rau muaj kev cuam tshuam loj heev ntawm cov khoom siv rau corrosion thiab oxidative influences. Stainless hlau alloys tiv taus rau feem ntau oxidizing acids thiab tuaj yeem tiv taus xeb ib txwm, tab sis qhov ntawd tsis tau txhais hais tias cov hlau yuav tsis tarnish dhau sijhawm. Cov hlau yuav tsum tau ua haujlwm txias kom tsim tau lub zog tensile ntau dua. Rau qhov hnyav welded stainless hlau seem, tom qab weld annealing yuav tsum tau muab siab tshaj corrosion kuj.

Qib 304L yog cov pa roj carbon tsawg ntawm 304 uas tsis tas yuav tsum muaj kev sib txuas ntawm kev sib txuas thiab yog li ntawd dav siv rau cov khoom ntsuas loj (kwv yees li 6 hli lossis loj dua). Cov qib carbon zoo tshaj 304H tuaj yeem siv rau qhov kub siab. Cov qauv austenitic kuj muab cov qhab nia zoo heev, txawm tias qhov kub thiab txias.

Ib pawg ntawm 304 / 304L S30400 / S30403 welded yeeb nkab xaj los ntawm peb los ntawm cov neeg siv khoom qub hauv Taiwan tau tsim nyob rau hauv qhov zoo thiab ntim thiab xa mus rau qhov chaw. Peb yog cov chaw tsim khoom thiab cov chaw muag khoom ntawm welded kav. Yog tias koj xav tau, thov hu rau peb!
