ASTM A959 Austenitic Stainless Steel Pipe

Product Description

ASTM A269 904L Seamless austenitic stainless steel tube

 

904L (N08904,14539) super austenitic stainless steel contains 14.0-18.0% chromium, 24.0-26.0% nickel

and 4.5% molybdenum.904L super austenitic stainless steel is a kind of low carbon, high nickel and

molybdenum austenitic stainless steel. It has good activation and passivation conversion ability, excellent

corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid,

formic acid, phosphoric acid, good pitting corrosion resistance in neutral chloride ion medium, and good

resistance to crack corrosion and stress corrosion. Used in various concentration of sulfuric acid under

70 ℃, under ordinary conditions of any acetic acid concentration, any temperature, resistance and

formic acid and acetic acid in mixed acid corrosion resistance is also very good.
