Original Abstract

The results of both the experimental investigation and the literary survey on the role of the tempering temperature within a wide range of mechanical properties is presented for selected ultra-high strength low alloy (UHSLA) steels of American (AISI 4340, 300M and Garrison NiSiCr) and Czech (P-LDHA and V-ROL N) provenance. The analysis confirmed the equivalence of steels 300 M and P-LDHA and their superiority among investigated steels. The optimum tempering temperature was proved to be 300 OC for prevailing majority of mechanical characteristics of all steels. The only exception is the steel V ROL N, where the optimum temperature is shifted down to 200 OC.
