Alloy 303 (UNS S30300) yog ib qho tsis sib nqus, austenitic, dawb-machining stainless hlau uas yog kev hloov kho ntawm 10% chromium -8% npib tsib xee stainless hlau tshwj xeeb uas tsim los nthuav tawm kev txhim kho machinability thaum tuav cov khoom zoo thiab corrosion -resistant khoom.
Lub alloy yog nonmagnetic nyob rau hauv lub annealed mob, tab sis tej zaum yuav ua me ntsis sib nqus raws li ib tug tshwm sim ntawm txias ua hauj lwm. Qhov sib ntxiv ntawm cov sulfur tsis zoo cuam tshuam qhov kev tiv thaiv corrosion ntawm 303 ua rau nws tsis tshua muaj zog dua 304 mus rau ib puag ncig me me corrosive.

Alloy 303 yog resistant rau me me corrosive ib puag ncig. Txawm li cas los xij, cov hlau tsis zoo corrosion kuj yog qis dua 304 hauv feem ntau cov ntawv thov. Nws cov corrosion kuj yog superior rau 416, lwm yam dawb-machining qib, tab sis yog me ntsis qis dua lwm yam 400 series stainless hlau uas tsis muaj leej faj ntau dua. Txhawm rau kom tau txais qhov zoo tshaj plaws corrosion kuj, nws raug pom zoo tias Alloy 303 raug kho tshuaj kom tshem tawm sulfides ntawm qhov kawg ntawm qhov chaw.
