Product Description

Ferronobium

Ferronobium is an iron alloy composed mainly of niobium and iron. It also contains impurities such as aluminum, silicon, carbon, sulfur, phosphorus, etc. According to the niobium content of the alloy, it is divided into FeNb50, FeNb60, and FeNb70. The iron alloy produced from niobium tantalum ore contains tantalum and is called niobium tantalum iron. Niobium iron and niobium nickel alloys are used as niobium additives in vacuum smelting of iron-based alloys and nickel based alloys

Application :

1. Mainly used for smelting high-temperature (heat-resistant) alloys, stainless steel, and high-strength low-alloy steel 2. Niobium plays a role in solid solution strengthening and carbide precipitation strengthening in high-temperature alloys, improving the yield strength and surface stability of high-temperature alloys 3. Application on third grade threaded steel The promotion of replacing vanadium with niobium has made progress. The primary effect of niobium, vanadium, and titanium in steel is to refine grain size and promote the separation and strengthening of carbon and nitride
