Effect of Alloying Elements on Tempered Martensite Embrittlement and Fracture Toughness of Low Alloy High Strength Steels

Abstract

A study was performed on the influence of various elements on the notch bend fracture toughness at 75F and -100F of .35%C, 3Ni-Cr-Mo-V martensitic steels tempered between 400 and 800F. The elements examined included C, Mn, Si, Cr, Ni, Mo, Co, V and Al. The overall variation in room temperature yield and tensile strengths for twenty-four steels was 155-230 ksi yield strength and 188- 288 ksi tensile strength.
