Highly stressed components with large cross sections for aircraft, automotive and mechanical engineering, such as propeller shafts, connecting rods, gear shafts, crankshafts, landing gear components. Heavy forgings, such as rotors, shafts and discs. For economic performance under severe dynamic stresses, parts must be designed for optimum strength.
Cr-Ni-Mo- steel for applications requiring high tensile and toughness values, in particular in large cross sections in the quenched and tempered condition. The molybdenum addition prevents the steel from being susceptible to temper brittleness.
