ALTA 1.2714 is Nickel-chrome-molybdenum-vanadium steel for hardening in the stream of air or in oil with high hardenability. The steel has high hardness after hardening, good resistance to the tempering, good toughness and good firmness during the heat. Is resists quick temperature changes and also thermal fatigue. The steel is well-workable during the heat and well-workable in the soft-annealed state.
Applications
²Hammer forging dies, hot forging tools
²Extrusion dies
²Large molds for plastic processing used in thermoplastics
