Abstract

The presented work is concerned primarily with experimental determination of the behaviour of normalised and quenched and tempered low-alloy steel 42CrMo4 (AISI4140) subjected to monotonic uniaxial tensile loading and determination of its monotonic parameters. Experiments were performed on standard specimens using a servo-hydraulic testing machine at room temperature. The behaviours of materials with differing hardnesses were analyzed and compared. After determination of principal monotonic parameters values, correlation was confirmed to exist between tempering temperature, i.e. achieved materials’ hardness, and the monotonic yield strength as well as the ultimate strength. Simple expressions are proposed for fast estimation of cited monotonic properties from hardness.
