Product Description

904L Stainless Steel Seamless Pipe

ASTM A790 UNS N08904 Seamless Pipe - Austenitic 904L OD 10-500mm Stainless Steel Pipe for Automobile Exhaust Systems

Product Specifications

00Cr20Ni25Mo4.5Cu	1.4539	904L

Material Features

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel contains copper to enhance resistance to strong reducing acids such as sulphuric acid. The material demonstrates excellent resistance to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic and offers superior formability, toughness, and weldability characteristics.

Fabrication Characteristics

Grade 904L stainless steels are high purity materials with low sulphur content. They can be machined using standard methods and readily bent to small radii under cold conditions. While subsequent annealing is typically unnecessary, it should be performed when fabrication occurs under severe stress corrosion cracking conditions.
