General Properties
Alloy 904L (UNS N08904) yog superaustenitic stainless hlau uas yog tsim los rau nruab nrab mus rau siab corrosion kuj nyob rau hauv ntau yam txheej txheem ib puag ncig. Kev sib xyaw ua ke ntawm cov ntsiab lus siab chromium thiab npib tsib xee, ua ke nrog ntxiv ntawm molybdenum thiab tooj liab, paub tseeb tias zoo rau kev tiv thaiv corrosion zoo heev.
Nrog nws cov chemistry heev alloyed - 25% npib tsib xee thiab 4.5% molybdenum, 904L muab cov tshuaj chloride zoo corrosion cracking kuj, pitting thiab dav corrosion kuj superior rau 316L thiab 317L molybdenum enhanced stainless hlau.
Muaj thicknesses rau Alloy 904L:
