Common Japanese brand
309S stainless steel woven wire mesh for ordinary and mechanical structure is classified by steel type:
　　(1) Austenite (2) Austenite-ferrite (3) Ferrite (4) Martensite, precipitation hardening Note: Precipitation hardening (precipitation strengthening): refers to a heat treatment process in which the solute atoms in the supersaturated solid solution are concentrated and (or) the particles dissolved therefrom are dispersed in the matrix, resulting in hardening. For example, austenitic precipitated stainless steel can obtain high strength by precipitation hardening at 400-500℃ or 700-800℃ after solution treatment or cold working. That is, the supersaturated solid solution of some alloys is placed at room temperature or heated to more.

309/309S stainless steel wire mesh application industry introduction
309/309S, 310/310S stainless steel is widely used in the heat treatment/processing industry due to its high temperature resistance and oxidation resistance. Because of this, these alloys are often processed into complex structures. The processability of carbon steel is generally considered the standard in metal forming operations. Austenitic stainless steel exhibits very different properties from carbon steel: austenitic stainless steel is more difficult to process and hardens very quickly. Although this does not change the processing methods we generally use, such as cutting, machining, forming, etc., these characteristics affect the specific details of these processing methods. Standard
 　　techniques for cutting and machining ordinary mild steel can also be used to process austenitic stainless steel with slight adjustments. However, austenitic stainless steel is more difficult to process and hardens very quickly. The fragments produced during the processing are fine and hard, and retain quite good ductility. The tools used for processing should be kept sharp and hard. For hardened areas, deep and slow cutting is generally used. Due to the low thermal conductivity and high coefficient of thermal expansion of austenitic stainless steels, heat removal and dimensional tolerances must be considered during cutting and machining.
 　　Austenitic stainless steels can be cold worked by bending, stretch forming, roll forming, hammering, flaring/flanging, spinning, fine drawing, hydroforming, etc. During processing, austenitic stainless steels tend to harden, which is manifested by the increasing forces required during processing. This means that more powerful forming equipment is required and ultimately limits the degree of formability.
 　　Because of various environmental and metallographic factors, the temperature range for hot working of 309 and 310 is relatively narrow. The initial temperature range for forging is 1800-2145°F (980-1120°C), and the end temperature cannot be lower than 1800°F (980°C). Working at too high a temperature will cause the alloy's hot plasticity to decrease due to environmental and metallographic factors, especially the formation of ferrite. Working at too low a temperature will form brittle secondary phases, such as sigma. After forging, the forging should be cooled quickly to dark heat.
