Stainless steel wire mesh is the most popular woven screen in the industrial world, it is well known for its corrosion resistance and strength.
Stainless steel wire mesh contains chromium and nickel in addition to steel. It is non magnetic in the annealed condition. After stainless steel has been woven , it may become slightly magnetic due to cold working.
The two basic metal types: alloy type 304 and type 316
T304 is the basic metal alloy ,and unless otherwise specified it is assumed that this type is acceptable, also to be called 18-8 due to 18% chromium and 8% nickel. T304 melts at 2600 degrees F(1430 C) but its maximum recommended temperature for continuous service is 1450 degrees F(790 C) and is used for intermediate service up to 1650 degrees F(900 C). its uses including: sorting and screening of abrasives, liquids, powders and other solids , it is the less expensive alloy but not as corrosion resistance as T316, it is the stronger of the two types.
Type 316 is a special alloys due to the addition of 2% molybdenum. This increase its resistance to corrosion by salts, acids and seawater. Also called 18-10 due to 18% chromium and 10% nickel. T316 melts at 2500 degrees F (1375 C) but it maximum recommended temperature for continuous service is 1500F(815 C) and is used for intermediate service up to 1650 degrees F(900 C) its uses including : processing of oils and foods, chemicals and pharmaceuticals.
