Rust in SS-304 wire mesh

WE ARE FACING A PROBLEM OF RUST ON SS-304 WIRE MESH. IT IS USED IN IRRIGATION FILTER. WE MOULD THE MESH WITH NYLON AND MAKE A CARTRIDGE FOR FILTRATION ELEMENT.

OUR SUPPLIERS DO NOT KNOW HOW TO PREVENT RUST . SO I WANT TO KNOW HOW TO PREVENT THE RUST AND GIVE ME A BETTER SOLUTION.

First- are you passivating the stainless steel? This is necessary to get good resistance to corrosion and rusting. It is simple and easy to do, and should give you what you need.

Although 304 is a fairly good grade of austenitic steel, we have seen a rapid decay in the quality of this grade of steel over the past years. So, there is always a possibility that the wire you are using is not of good quality, but we cannot say that this is the case.

Let us know if we can help.
