Kev piav qhia
Qib 904L stainless hlau yog super austenitic stainless hlau uas muaj cov tshuaj carbon tsawg.
904L steel yog ntxiv nrog tooj liab los txhim kho nws cov kev tiv thaiv kom muaj zog txo cov acids, xws li sulfuric acid.Lub alloy tseem tiv taus kev ntxhov siab corrosion cracking thiab crevice corrosion.
Qib 904L yog non-sib nqus, thiab muaj cov qauv zoo heev, toughness thiab weldability.
