Ferroniobium
Functioning primarily as a microalloying agent in high-strength, low-alloy (HSLA) steel, ferroniobium (FeNb) contains around 35% iron and 65% niobium. Adding a small amount of this alloy can make a significant difference in a material’s properties.
In low-carbon steel facilities, a single pound of ferroniobium increases precipitation hardening and grain refinement. These alterations lead to significant material improvements, such as increased fatigue resistance, weldability and strength. Compared to all other steel microalloying elements, ferroniobium creates these advantages to the greatest extent.
