This report evaluates the elevated temperature strength properties of carbon-moly steel, and various modified versions of that steel commonly identified as manganese-molybdenum or manganese-molybdenum-nickel steels. The data that have been evaluated encompass test results previously included in ASTM Data Series DS 6 (1953) and DS6-S1 (1966), and previously unpublished test results gathered by The Metal Properties Council.

Materials covered include carbon, alloy and stainless steels; alloy cast irons; high-alloy cast steels; superalloys; titanium and titanium alloys; refractory metals and alloys; nickel-chromium and nickel-thoria alloys; structural intermetallics; structural ceramics, cermets, and cemented carbides; and carbon-composites.
