304 and 316 stainless steel wire meshs are two different materials. From a chemical point of view, they only contain different amounts of nickel and the like. Let's take a closer look.
316 stainless steel: 18cr-12ni-2.5Mo contains molybdenum (Mo), which is not available in 304. The corrosion resistance of 316 is better than 304. Molybdenum can further improve the atmospheric corrosion resistance, especially the corrosion resistance of the atmosphere containing chlorides. It is the second widely used steel after 304. Its main characteristics are that it can withstand acid and alkali and high temperature. 316 stainless steel also has a significant characteristic that there is no thermal expansion and contraction at all.
The main ingredients of 304 stainless steel and 316 stainless steel are about 16-18% chromium, but 304 stainless steel
contains 9% nickel uniformly, and 316 stainless steel contains 12% nickel uniformly. Nickel can improve high temperature durability, improve mechanical properties, Improves oxidation resistance. Therefore, the nickel content of the data directly affects the comprehensive performance of the data.
304 (0Cr18Ni9) stainless steel is austenitic stainless steel, which cannot be strengthened by heat treatment, and cannot be quenched like carbon steel, and has no magnetic properties. The various mechanical properties of 304 are comparable, with considerable ability to resist corrosion and high temperature. It is widely used as stainless heat-resistant steel. 316 (0Cr17Ni12Mo2) contains molybdenum (Mo), which is not available in 304. The corrosion resistance of 316 is better than 304. Molybdenum can further improve atmospheric corrosivity, especially the corrosion resistance of chloride-containing atmospheres.
304 stainless steel: 304 stainless steel wire mesh is a universal steel. As a universal steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, and no heat treatment and hardening. (Non-magnetic, use temperature -196 ℃ ~ 800 ℃).
