2. 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.

 

3. 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.

 

4. 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

 

5.Surface finish

 

No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish.

No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using [large diameter] polished rolls.

Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.

No. 3 Finish is characterized by short, coarse, parallel polishing lines, which extend uniformly along the length of the coil.

No.4 Finish is characterized by short, parallel polishing lines, which extend uniformly along the length of the coil. It is obtained by mechanically polishing a No. 3 finish with gradually finer abrasives.

No.7 Finish has a high degree of reflectivity and a mirror-like appearance. A No. 4 finish that has been polished to 320-grit is buffed for up to 10 minutes but existing grit lines are not removed. The remnants of fine polishing lines can generally seen by an observer standing several feet from a panel.
