Quenched and tempered steel with high temperability and toughness thanks to the high chromium content. It can be quenched and tempered at high resistance values and offers hardness consistency and uniformity. Generally used for pinions and shafts. Has average machinability on tool machines. Can be nitrided at the quenched and tempered state to increase resistance to wear and the fatigue limit. Uses: 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.

This is the steel most commonly used in northern Europe when the addition of nickel is required by the severe use conditions. It has an elevated temperability thanks to the presence of significant levels of nickel and chromium: it is even suitable for the construction of large pieces that, at the quenched and tempered state, have well transformed structures down to the core.
