NIOBIUM APPLICATION, METALLURGY AND GLOBAL TRENDS IN PRESSURE VESSEL STEELS
Niobium-containing high strength steel materials have been developed for a variety of pressure vessel applications.Through the application of these Nb-bearing steels in demanding applications,the designer and end user experience improved toughness at low temperature,excellent fatigue resistance and fracture toughness and excellent weldability.These enhancements provide structural engineers the opportunity to further improve the pressure vessel design and performance.The Nb-microalloy alloy designs also result in reduced operational production cost at the steel operation,thereby embracing the value-added attribute Nb provides to both the producer and the end user throughout the supply chain.For example,through the adoption of these Nb-containing structural materials,several design-manufacturing companies are considering improved designs which offer improved manufacturability,lower overall cost and better life cycle performance.
