Alloy 904L (UNS N08904 904 steel phaj) yog superaustenitic stainless hlau uas UNS N08904 904 steel phaj 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.
Cov ntsiab lus siab ntawm cov ntsiab lus alloying hauv UNS N 08904 904 steel phaj muab cov hlau tshwj xeeb zoo tiv thaiv corrosion tsis zoo.

UNS N {{0}} steel phaj yog Ameslikas tsim los tiv thaiv ib puag ncig uas muaj dilute sulfuric acid, thiab yog ib qho ntawm ob peb stainless hlau uas, ntawm qhov kub txog li 95 degree F (35 degree), muab kev tiv thaiv tag nrho hauv xws li ib puag ncig nyob rau hauv tag nrho cov concentration ntau ntawm 0 mus rau 100 feem pua. UNS N08904 904 steel phaj kuj muaj kev tiv thaiv zoo rau ntau lwm cov inorganic acids, xws li phosphoric acid thiab feem ntau cov organic acids. Txawm li cas los xij, cov kua qaub thiab cov kua qaub uas muaj halide ions tuaj yeem ua rau muaj kev txhoj puab heev, thiab corrosion kuj ntawm 317L, 317LMN thiab 904L yuav tsis txaus.
