High performance bridge steels

Steel producers respond to demand for high performance bridge steels with Niobium

Niobium-containing bridge steels are being produced by steelmakers to respond to the demand for better performing, value-added bridge materials. These steels possess a combination of exceptional properties – high strength, excellent weldability, impressive toughness at low temperature, desired ductility, superb corrosion resistance and high formability. High performance steels that include weathering steels for bridge structures, possess an optimized balance of these primary properties, providing a cost-effective product for bridge structures at strength levels from 355MPa to 700MPa, and demonstrating excellent corrosion resistance.
