In the fields of steelmaking, casting, and surface treatment, the choice of ferroalloy directly affects product quality and cost. However, most companies are still wandering between traditional ferrochrome (such as low carbon ferrochrome) and pure metals, while ignoring ferrochrome nitride (Nitrided Ferrochrome ), an “all-round material” that combines performance and cost advantages. As a manufacturer of Ferrochrome nitride for 17 years, I will tell you the 3 reasons why it has become the king of cost performance.
Ferrochrome nitride can save certain production costs
The core advantage of nitrided ferrochrome lies in its ultra-high surface hardness (up to HV 2200), which is 3-5 times higher than ordinary ferrochrome. This means: If mechanical parts are produced, they will last longer: for example, in the hammerhead of a mining crusher, the wear rate is reduced by 60% after using Ferrochrome nitride coating.
Substitute the scarce element nickel: Nitrogen is about 30 times more effective than nickel in expanding the austenite zone. It can partially replace scarce and expensive nickel in the production of chromium-manganese and chromium-manganese-nickel stainless steel. It not only ensures the performance of steel but also reduces production costs, while other ferroalloys generally do not have such an effective function of replacing nickel.
Ferrochrome nitride is more resistant to corrosion and oxidation
In the traditional solution, chromium plating is required for corrosion resistance and nickel is added for oxidation resistance – Ferrochrome nitride simultaneously solves two major problems through the nitrogen-chromium compound layer:
Salt spray test data: In a 5% NaCl environment, the corrosion resistance time of Ferrochrome nitride coating reaches 2000 hours, far exceeding the 500 hours of electroplating chromium.
High temperature performance: In an oxidizing environment of 800°C, the oxidation resistance of Ferrochrome nitride is twice that of 304 stainless steel.
Ferrochrome nitride is easier to melt and dissolve in molten steel
Ferrochrome nitride is easy to melt and dissolve during the steelmaking process, and can be quickly and evenly integrated into the molten steel, which is beneficial to improving smelting efficiency and shortening smelting time. In contrast, some ferroalloys may have problems such as slow melting and uneven dissolution, which affects the stability and production efficiency of the steelmaking process.
