Fe-Nb

1. Introduce

– Alloy formed by combining iron and niobium (about 60~80%)

– Usually obtained from the thermite process, which reduces a mixture of iron oxide and niobium oxide to aluminum at high temperatures

– Excellent alloying agent used in high strength low alloy (HSLA) steels
→ High strength low alloy (HSLA) steels with significantly improved properties are obtained when niobium is added to steel at 0.1% or less
→ Used as an additive in steel manufacturing to improve strength and toughness

– Mainly used in the production of materials designed to withstand extreme temperatures and mechanical stresses

2. Property

– Excellent strength, toughness, ductility, cryogenic toughness, corrosion resistance, weldability, creep resistance, and high temperature erosion resistance
