ASM International, formerly known as the American Society for Metals, is an association of materials-centric engineers and scientists.

[4] After World War I, the Chicago group seceded and formed the American Steel Treaters Society.

[4] In 1920 the local chapters were reunified into the new American Society for Steel Treating (ASST).

ASM provides several information resources, including technical journals, books, and databases.

[5] Six affiliate societies focused on specific areas of materials science also fall under the ASM umbrella: Each society is led by volunteers, produces specific technical content for members, and holds its own international event.
