Mostly used Hastelloy for sintered wire mesh is the Hastelloy C series. It is a nickel-molybdenum-chromium alloy with tungsten addition which brings outstanding corrosion resistance in various of harsh environment including hypochlorite, wet chlorine gas and chlorine dioxide solutions. Hastelloy C-276 (UNS N10276) is especially resistant to pitting and crevice corrosion, even in the environment of sulphuric, acetic, phosphoric and nitric acids. Hastelloy C-276 also has good resistance to formation of grain-boundary carbide precipitates during welding.
C-22 (UNS N06022) has better overall corrosion resistance under high temperature, and even more pitting resistance.
Hastelloy C has great resistance to solutions of oxidizing chloride salts including iron and copper ion. It also outperforms in seawater, especially under crevice conditions where other frequently used alloys fails, such as 316L 904L stainless steel, Monel 400, Inconel 625.
Hastelloy C276 C22 sintered wire mesh
Hastelloy C-276 and C-22 sintered wire mesh have micron rating range of 5-200 microns.
Hastelloy perforated metal is also available, thus sintered wire mesh with perforated metal can be made of full Hastelloy materials.
