ASTM DIN EN Standard 904L 1.4539 Stainless Steel Pipe Tube OD6-406mm SCH40

1. Products Details

Features

Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Chemical Composition

Proprerties

Fabrication

Grade 904L stainless steels are high purity steels with low sulphur content. They can be machined using any standard methods. These grades can be readily bent to a small radius under cold conditions. Although subsequent annealing is not required in most cases, it should be carried out when the fabrication is performed under severe stress corrosion cracking conditions.

Application

Some of the major applications of grade 904L stainless steels include:

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
