Formed in January 2004 from the merger of the Iron & Steel Society and the Association of Iron and Steel Engineers, AIST is proud to be the #1 source for all your steel-related needs. We encourage you to explore all that we have to offer. From technology-based Operating Committees to our local Member Chapers, the opportunities to network with others and expand your technical know-how abound. Each year we offer two major conventions along with many specialty conferences that will help you get the most out of your membership.
