This presentation by ArcelorMittal will be a technical seminar explaining the benefits of ASTM A913 steel, which has been produced by the company for more than 25 years and is unique in its production process as its high yield strength, excellent toughness and outstanding weldability is achieved through a Quenching and Self-Tempering (QST) process. The material – which is available in grades 50, 65 and 70 – is widely approved by major structural design and fabrication codes throughout the world. Sections produced from this material range from W14x90s to the world’s largest jumbo wide-flange shapes, W36x925s! The presentation will provide an outline of the technical aspects of the materials; an overview of the production, availability, and delivery process; and information on some interesting case studies for which use of these products has resulted in material cost savings and improved structural efficiency.
