Wire gauze, particularly stainless steel wire gauze for supporting filter material layer in bellow of filter, e.g. hydraulic oil filter, has warp wires, which are cutting across weft wires
The wire gauze has warp wires (7), which are cutting across weft wires (8). The warp wires and the weft wires have different resistance to flexural stress. The weft wires have a high resistance to flexural stress as the warp wires. The weft wires have small nickel content as the warp wires. The weft wires consists of a chromium steel and the weft wires consists of a nickel-chromium steel.
