Product Description

Polished Etched Stainless Steel Sheets / Bright 904l Stainless Steel Sheet

 

904l Stainless Steel Sheet 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.

904l Stainless Steel Sheet 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.

 

904l Stainless Steel Sheet 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.

 

904l Stainless Steel Sheet 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

904L is an austenitic stainless steel.In comparison to 316L, its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids and in particular its copper addition gives it useful corrosion resistance to all concentrations of sulphuric acid. Its high alloying content also gives it greater resistance to chloride stress corrosion cracking, but it is still susceptible. Its low carbon content makes it resistant to sensitization by welding and which prevents intergranular corrosion.

It has applications in piping systems, pollution control equipment, heat exchangers, and bleaching systems.

 


What is grade 904L stainless steel?


Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
