ASTM A 909/A 909M - 06 Standard Specification for Steel Forgings, Microalloy, for General Industrial Use

American Society for Testing and Materials (ASTM). Current edition approved Dec. 1, 2006. December 2006. Originally approved in 1992. Last previous edition approved in 2003 as A 909 – 03. 4 p. This specification covers wrought, microalloyed carbon steel forgings for industrial use. Microalloyed steels develop their properties by the addition of small amounts of microalloying elements such as vanadium, columbium, titanium, or molybdenum. The properties may be influenced also by control of the hot working process and temperature and by control of the subsequent cooling rate.
