Notes:
Summary 1. The addition of 0.10–0.15% Ce (calculated) to carbon steel No. 20, St. 3, and KSt. 3 improves their macrostructures, considerably decreases the concentrations of sulfur and oxygen, and increases the resilience and the ductility at high temperatures. 2. The critical embrittlement temperature decreases from −30 to −40°Cto −60 to −70°C. 3. The sensitivity to stress concentrations and the resistence to mechanical aging, and also the weldability and the resistence of welds to vibrations in MSt. 3 steel are the same with and without rare-earth metals.
