The rapidly growing use of microalloy forging has been encouraged by recently developed microalloy grades and by the introduction of a comprehensive, new ASTM specification A-909 Standard Specification for Steel Forgings, Microalloy, for General Industrial Use. This specification includes compositions for achieving at least four (4) strength and hardness levels. It is intended to make it easier for designers to select the proper combination of steel composition, processing and properties for MA forgings.
