N2 - Hot work tool steels like AISI H11 is used mainly for high temperature metal forming operations. Many operating difficulties and loss of production arise through die wear resulting in die failure. This work mainly focuses on the study of cryogenic treatment and its effect on wear performance of H11. Specimens of H11 were hardened (1293 K), double tempered (773 K each for 2 h), cryotreated (88 K) for varying periods viz., 8, 16, 24, 32 h and then soft-tempered at varying temperatures viz., 323 K, 373 K, 423 K, 473 K. Characterization techniques like SEM, hardness and Pin-On-Disc wear test were employed. Standardized parameters were analyzed for shift in wear regimes and finally a correlation between soft tempering temperature (STT) and the conventional tempering temperature (CTT) has been established.
