904Lyog ib tug untenenic stainless hlau. Nws yog softer tshaj 316L,[1] [2]thiab nws cov molybdenum ntxiv muab nws superior tsis kam mus rau localized nres (pitting thiab crevice corrosion) los ntawm chlorides thiab ntau dua kuj txo acids; tshwj xeeb, nws cov tooj liab ntxiv muab nws cov txiaj ntsig zoo corrosion rau tag nrho cov ntsiab lus ntawm sulfuric acid. Nws cov ntsiab lus siab alloying kuj tseem ua rau nws ua haujlwm ntau dua rau chloride kev nyuaj siab corrosion cracking, tab sis nws tseem raug. Nws cov ntsiab lus tsis tshua muaj carbon ua rau nws resistant rau rhiab heev los ntawm vuam thiab uas tiv thaiv intergranular corrosion.
Nws muaj cov ntawv thov hauv cov kav dej, cov cuab yeej tswj kev ua qias tuaj, cov khoom siv hluav taws xob sib hloov, thiab cov tshuab bleaching.
Omega SA tau sim nrog 904L lossis 'Uranus Steel' nrog PloProf dhia saib hauv xyoo 1971-72. Kev tshoov siab los ntawm Fabkis lub tuam txhab dhia dej hiav txwv tob GNEE, uas siv cov hlau no hauv lawv lub tswb nrov vim muaj kev tiv thaiv corrosion zoo tshaj hauv dej ntsev.[8]Xyoo 1985, Rolex pib siv 904L qib steel hauv nws cov watches.[9]Ntawm ib sab nws corrosion tsis kam, saib cov tuam ntxhab, xws li Rolex, kuj tseem xaiv cov hlau uas tsis tshua muaj zog siv los ntawm Seiko, Omega, thiab Tudor
