Description

Duplex 904l 2205 2507 Square Solid Stainless Steel Bar

High temperature and corrosion resistance, long service life, 1 ton minimum order

904L
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 belongs to low carbon high nickel and molybdenum austenitic stainless steel, which is stainless and acid resistant.
It has good activity-passivation conversion ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid, good pitting resistance in neutral chlorine-containing medium, and good crack corrosion resistance and stress corrosion resistance.
Suitable for various concentrations of sulfuric acid below 70℃, under normal pressure to withstand any concentration, any temperature of acetic acid, and acid and acetic acid mixed acid corrosion resistance is also very good.

2205
Duplex stainless steel 2205 standard no. : ASTM A240/A240M–01 duplex stainless steel 2205 is a composite stainless steel consisting of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloys.
It has high strength, good impact toughness and good overall and local resistance to stress corrosion.
