Abstract

To simplify the manufacture of pressure vessels and to enhance the properties thereof, a steel is proposed which has a composition of 0.15 - 0.26% of carbon 1.25 - 2.00% of manganese 0.2 - 0.5% of silicon at most 0.02% of phosphorus at most 0.005% of sulphur 0.1 - 0.5% of molybdenum 0.010 - 0.035% of titanium 0.0030 - 0.0100% of N 0.001 - 0.003% of boron 0 - 0.04% of niobium, the remainder being iron and usual impurities, the titanium content/nitrogen content ratio being adjusted to between 3.6 and 6.5. The invention also relates to a heat treatment process for the vessels manufactured from this steel.
