904L Stainless Steel Wire Mesh

904L Stainless Steel Wire Mesh supplied by Lawrence Sintered Metals is a non-stabilized low carbon high alloy austenitic stainless steel. The addition of copper to this stainless steel sintered wire mesh grade gives it 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 is excellent for fabricated filters because this type of stainless steel wire mesh has good weldability and formability. The metal structure also gives this grade excellent sturdiness, even down to extremely low temperatures.

904L Stainless Steel sintered wire mesh has outstanding activation and passivation ability, excellent corrosion resistance, good corrosion resistance in non- oxidizing acid such as sulfuric acid, acetic acid, formic acid and phosphoric acid.

Common applications for SS904L mesh filters include desalination plants, ballast water management systems on oceangoing vessels, oil wells, and any filtration application where higher corrosion resistance than SS316L is required. The typical Pitting Resistance Equivalent Number (PREN) for SS904L is around 34, whereas a typical PREN for SS316L is around 23.

We typically offer SS904L as sintered wire mesh filters, either in flat sheets or rolled and welded into cylindrical filters. They can be composed of either multi-layer sintered laminates with just wire mesh, or multi-layer sintered laminates composed of wire mesh diffusion bonded to perforated metal for increased mechanical strength and abrasion resistance. The sintered laminate consisting of wire mesh bonded to perforated metal, rolled and welded into cylinders, is especially useful in self-cleaning water filters with interior nozzles.
