Influence of the content of chromium in low-carbon bainitic-martensitic steels on the efficiency

Abstract

The effect of chromium content on phase transformations in low-carbon high-strength steel for shipbuilding has been studied. Under industrial conditions, two rolled sheets 50 mm thick were manufactured from steel with a chromium content of 1.08% and 0.42% using hot rolling technology, followed by furnace hardening and high-temperature tempering, standard mechanical properties and performance characteristics were determined. With the help of optical and transmission electron microscopy, the structural features of steel were revealed.
