What is the difference between nickel-containing stainless steel wire mesh and nickel-free stainless steel wire mesh? The answer must be different. The corrosion resistance of nickel-containing is better than that of nickel-free. The price of nickel-containing and nickel-free is also different to some extent.

What our customers need to know is that nickel is an excellent corrosion-resistant material and an important alloying element of alloy steel. Nickel is an element that forms austenite in steel, but low carbon nickel steel needs to obtain a pure austenite structure with a nickel content of 24%; and only when nickel content is 27% does the steel resist in certain media The corrosion properties have changed

significantly. Therefore, nickel cannot constitute stainless steel alone. However, when nickel and chromium are present in the stainless steel wire mesh at the same time, nickel-containing stainless steel has many valuable properties.

Nickel-free stainless steel has two kinds of martensite and ferrite, the main characteristics are brittle and magnetic. Nickel-containing stainless steels are mainly austenitic and precipitation hardening stainless steels, which are mainly characterized by better corrosion resistance and non-magnetic or weak magnetic. Another kind of micro-nickel is austenitic-ferrite duplex stainless steel. One of the main reasons for adding nickel to stainless steel wire mesh is the formation of austenite crystal structure to improve the properties of stainless steel such as corrosion resistance, plasticity, weldability and toughness.

Stainless steel wire mesh is selected to be nickel-containing, more tough, acid and alkali resistant, high temperature resistant, and resistant to oxidation.From:https://www.cnmaishi.com/news/industrial-news/stainless-steel-wire-mesh-contain.html
