High hardenability steel that reaches high mechanical resistance of 300 Ksi or 210 kgf/mm2, with good toughness. Used in the manufacturing of aircraft and helicopter landing gear parts (ex.: high mechanical resistance shafts), devices for aircraft stairways and engine jackets for satellite launch vehicles (SLV).
