AL Tech 416-F is one variation of AISI Type 416, one of the staple alloys for the free-machining industry. It offers some of the fastest machining speeds, but contains lower carbon and nitrogen than Types 416-EZ (Alloy Digest SS-665, December 1996) and 416-EZR (Alloy Digest, SS-667, January 1997) and may not heat treat to some specification levels. This datasheet provides information on composition and physical properties. Filing Code: SS-670. Producer or source: AL Tech Specialty Steel Corporation.
