ASTM A 240 904L DIN1.4539 X1NiCrMoCuN25-20-5 Stainless Hlau Phaj Sheet

Product Description

Qib 904L stainless hlau yog ib qho tsis muaj -stabilized austenitic stainless hlau nrog cov ntsiab lus carbon tsawg. Qhov no high alloy stainless hlau yog ntxiv nrog tooj liab los txhim kho nws cov kev tiv thaiv kom muaj zog txo acids, xws li sulfuric acid. Cov hlau kuj tseem tiv taus kev ntxhov siab corrosion cracking thiab crevice corrosion. Qib 904L tsis yog- sib nqus, thiab muaj cov qauv zoo heev, toughness thiab weldability.

Qib 904L muaj cov khoom xyaw kim heev, xws li molybdenum thiab npib tsib xee. Niaj hnub no, feem ntau ntawm cov ntawv thov uas siv qib 904L yog hloov los ntawm qis- nqi duplex stainless hlau 2205.
