Product Description

ASME SB677, ASTM B677 TP904L (UNS N08904) Stainless Steel Seamless Pipe

 

Wenzhou Shangle Steel Co., Ltd. (Shangle) founded in 2017,is a comprehensive company integrating industry and trade.As a leading supplier of stainless steel products in Wenzhou, it has a wide range of products in stock that have been rigorously tested and are ready to be shipped.

 

Description :

TP904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. It is also highly resistant to chloride attack - both pitting / crevice corrosion and stress corrosion cracking. This grade is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. 904L does have very substantial contents of the high cost ingredients nickel and molybdenum. Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by duplex stainless steel 2205 (S31803 or S32205), so it is used less commonly than in the past.
