Appendix 1a: ASTM Standard A255-89 Method for Calculating Hardenability from Composition
-
Published:1996
Abstract
This chapter discusses the method for calculating hardenability from composition. It contains tables listing multiplying factors, carbon content, initial hardness, and 50% martensite hardness. The tables also list Jominy distance for 50% martensite vs. DI (in. and mm), boron factors vs. % carbon and alloy factor, and distance hardness dividing factors for non-boron and boron steels (in. and mm).
