904L Austenitic Stainless Steel Filter Screen UNS N08904 Superior Filter Performance
UNS N08904 904L Austenitic Stainless Steel Woven Wire Mesh Filter Screen
Product Description
SS904L stainless steel wire mesh is a non-stabilized low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.
It is also highly resistant to chloride attack – pitting / crevice corrosion and stress corrosion cracking.
904L Stainless Steel is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
