The Association for Iron and Steel Technology (AIST) is a non-profit professional organization focused on promoting the international iron and steel industry through networking and education. The AIST has over 15,000 members in 70 countries, though the majority of its members are from North America, reflecting its historical link to the American Steel industry. The AIST was formed from a merger from two older organizations, the Association of Iron and Steel Engineers and the Iron and Steel Society in 2004. The AIST is a member organization of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME). The head office of the organization is in Warrendale, Pennsylvania, where it shares a building with The Minerals, Metals & Materials Society (TMS). From these offices is published the monthly Iron and Steel Technology magazine. The Association also runs an international conference each year called AISTech. The AIST also offers training courses and local events organized by its various chapters and committees.
