Mechanical Properties of Woven Metal Mesh Used for Manufacturing Porous Net Materials from 12Kh18N10T Steel

This work presents the nomenclature of woven square mesh and filter mesh that are most frequently used in filtering techniques as well as for manufacturing porous net materials. It is shown that mechanical properties of metal mesh and net porous materials under tension depend not only on their elongation but also on the design, relative position in the material and percent reduction in the process of pressure welding of the mesh wires. A method of constructing stress-strain diagrams based on calculations and experiments is proposed. It uses the similarity of geometrical parameters of one type of wire weaving as a basis for determining the strength of a certain type-size mesh with a specified value of percent reduction in the process of pressure welding. Analytical dependencies are obtained that describe the influence of the mesh geometrical parameters and the percent reduction on the strength of the 12Kh18N10T steel porous net materials in the process of pressure welding. The results of the theoretical research and experiments can be used for designing and manufacturing products made of porous net materials as well as for strength calculations of constructions operating under uniaxial tension.
