    Abstract

    The fracture toughness of steels with good retention of hardness at elevated temperatures (CarTech EX00053, Timken CBS 600 and 1000M, and Vasco X-2M) was compared with that of conventional carburizing steels (EX55, AISI 4820, 8620, and 9315). The short-rod method was used to determine short rod/short bar fracture toughness KIcSR between 22 and 400°C. Wide variations in fracture toughness were observed over this temperature range. The toughness of EX00053 and CBS 1000M increased sharply between 22 and 100°C with the former having the highest toughness of any of the steels studied.
