Cr-Fe Nitride Cored Wire

Cr-Fe Nitride Cored Wire Utilisation
Ferro chromium ntride cored wire is widely used in smelting nitrogen-bearing steel in electric furnaces and oxygen converter.

Nitrogen is an austenitic forming element, which is added as a component of chrome-manganese and chrome-manganese nickel stainless steel to replace the scarce nickel.

Advantages of Ferro Chrome Nitride Cored Wire
1. Improve the strength and plasticity of steel, enlarge the austenite zone, refine grain and improve its machining performance.
2. It can partially replace the nickel to reduce the cost.

FAQ of Cr-Fe Nitride Cored Wire
In which field is ferro chromium nitride mainly used?
As a new type of nitriding material, ferro chromium nitride is often used as alloy additive, which is widely used in the smelting production of special steel such as nitrogen-containing stainless steel, corrosion-resistant steel, heat-resistant steel, alloy steel and so on.

What is the composition of ferro chromium nitride?
Ferro chromium nitride is mainly composed of CrN, Cr2N, Fe4N and other nitrides. In addition, the complex nitride (Cr, Fe) 2n (1-x) of ferrochrome may be formed. The main factors affecting the phase composition are nitriding medium and nitriding temperature. The stability of chromium nitride is higher than that of iron nitride.

What is the development prospect of ferro chromium nitride？
At present, more and more attention has been paid to the production of low nickel austenitic stainless steel by replacing nickel with nitrogen. Nitrogen can make the steel have high strength and high corrosion resistance, and can keep the plasticity of the steel in a good level. At present, ferro chromium nitride, as a new type of nitriding material, has received great attention. Ferro chromium nitride is an excellent choice to save energy and reduce pollution.
