Stainless hlau qib 317L yog ib qho qis carbon version ntawm qib 317 stainless hlau. Nws muaj tib lub zog thiab corrosion kuj zoo li 317 steel tab sis tuaj yeem tsim cov welds muaj zog dua vim cov ntsiab lus tsis tshua muaj carbon.
ASTM A312 TP317L (UNS S31703) yog molybdenum-cov kabmob austenitic stainless hlau uas muaj zog tiv thaiv tshuaj tua kab mob zoo li piv rau cov pa chromium-nickel austenitic stainless hlau xws li Alloy 304. Tsis tas li ntawd, Alloy 317L muaj kev ntxhov siab ntau dua,- -rupture, thiab tensile lub zog ntawm qhov kub siab tshaj li cov pa stainless hlau. Nws yog cov pa roj carbon tsawg lossis "L" qib uas muab kev tiv thaiv rau rhiab heev thaum vuam thiab lwm yam txheej txheem thermal.
