Stainless Steel Handles Extreme Challenges

Every Major Wire screen media solution is available in a stainless steel wire option that holds up better against highly abrasive material and protects against severe blinding and clogging problems. By adding 11% or more chromium to steel, a stainless steel alloy becomes non-staining under most conditions that corrode plain steel. In addition, alloys containing chromium and nickel are not magnetic when they are annealed, so material passes through better instead of sticking to the wire. For the most severe applications, we offer two types of stainless steel woven wire:

Type 304: The most common type of stainless steel wire available, it is sometimes referred to as “18-8” (18% chromium, 8% nickel). Type 304 is comparable to high-carbon wire in ductility, wear resistance and tensile strength, withstands outdoor exposure without rusting and resists oxidation at temperatures up to 1,400 degrees F (760° C).

Type 316: It is stabilized by the addition of 2% molybdenum. Like Type 304, Type 316 is an “18-8” alloy, but it has better resistance to pitting and corrosion than Type 304 where brines, sulphur-bearing water or chlorides are present. It also has the valuable property of high creep strength at elevated temperatures.

Major Wire’s stainless steel screen media is available in .025-inch (.63 mm) to .375-inch (9.5 mm) wire diameters.
