Product Description

ASTM B677 UNS N08904 904L Stainless Steel Tube

ASTM A790 UNS N08904 seamless 904L stainless steel pipe with outer diameter range of 10-500mm, specifically designed for automobile exhaust pipe applications.

Material Specifications

China GB	BESN	ASTM
00Cr20Ni25Mo4.5Cu	1.4539	904L

Key Features

• Non-stabilized austenitic stainless steel with low carbon content

• Copper addition enhances resistance to strong reducing acids like sulphuric acid

• Excellent resistance to stress corrosion cracking and crevice corrosion

• Non-magnetic properties with superior formability, toughness, and weldability

Fabrication Characteristics

Grade 904L stainless steel features high purity with low sulphur content, enabling machining using standard methods. The material can be readily cold-bent to small radii. While subsequent annealing is typically unnecessary, it is recommended for fabrication under severe stress corrosion cracking conditions.

Applications

Wiring in electrostatic precipitators
Oil refinery components
Seawater cooling devices
Gas scrubbing plants
Pulp and paper processing industries
Acetic, phosphoric and sulphuric acid processing plants
