Introduction

Super Alloy 904L Wire Mesh is well-known for its UNS equivalent  S08904 wire mesh and DIN number 1.4539 Mesh.

This alloy is a non-stabilized austenitic stainless steel with low carbon content. The addition of copper elements helps to develop resistance to sulphuric acid and other reducing agents in both aggressive and mild conditions. 
904L alloy screen mesh products have good resistance to general corrosion and much other corrosion including pitting & crevice corrosion, intergranular corrosion, and stress corrosion cracking.
Grade 904L mesh is non-magnetic, and it has good formability, toughness, and weldability.  With high amounts of expensive ingredients, such as molybdenum and nickel it performs well in warm seawater and prevents chloride attacks. 

METART manufactures 904L woven wire mesh up to 200x200 for plain weave patterns, 325x325Mesh for twill weave patterns, and 250x2400Mesh for twill dutch weave.
