HG20615 duplex stainless steel ASTM A182 F904L LWN flange L=229MM
1. Duplex stainless steel 904L flange Introduction
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.
