Why does stainless steel mesh not rust?

Stainless steel wire rope mesh is widely used in zoos, architectural gardens, decorative protection and other fields because of its gorgeous appearance, corrosion resistance, sturdiness and durability. We only know the tip of the iceberg of stainless steel rope nets, both in use and craftsmanship. Stainless steel wire mesh has advantages over other metal wire meshes in terms of design and application.

We know that there are various specifications of stainless steel rope nets, the main materials are 304, 304L, 316, 316L, and different materials contain different chemical compositions. The chemical composition of stainless steel rope net is chromium, nickel and molybdenum. The comprehensive content ratio of carbon and other elements. Chromium can quickly form a dense passivation film on the steel surface to prevent the steel surface from chemically reacting with oxygen, moisture and its acid, alkali, and salt in the atmosphere to cause discoloration or corrosion, which greatly enhances its anti-rust function.

When adding chromium to steel products, adding an appropriate amount of nickel, molybdenum and other alloying elements can further improve its plasticity, toughness and corrosion resistance, and its rust resistance will be stronger. Third, the carbon content in stainless steel is also important. The higher the carbon content, the lower the rust resistance. Conversely, the lower the carbon content, the stronger the anti-rust performance.
