The differences of 316L ss mesh and 904L ss mesh

316l and 904l are both stainless steel material while they differ mainly in the content of chromium content, copper content and some precious alloy contents. The higher contents of alloys render 904l ss mesh screen better corrosion resistance than 316l stainless steel mesh products.

Materials: 00Cr20Ni25Mo4.5Cu

Weaving Types Applied: Plain woven, twill woven, Dutch woven ( Dutch plain and Dutch twill)

Standards: ASTM A276, A479, B649, GB.

904L ss wire mesh showing excellent property in following work environments:

Where excellent corrosion resistance in the non-oxidizing acid such as sulfuric acid, acetic acid,formic acid, phosphoric acid is demanded;

Where good corrosion resistance in neutral medium chlorine iron is demanded;

Where good pitting resistance, good resistance to crevice corrosion and stress corrosion is demanded;

Various concentration of sulfuric acid under 70 degree centigrade.

Application Field

904L steel is commonly used in petroleum, petrochemical equipment,sulfuric acid storage and transportation equipment, sea water treatment plant, water heat exchanger, papermaking equipment, sulfuric acid, nitric acid equipment, pharmaceutical industry and other chemical equipment, pressure vessel, food equipment and marine uses.
