| 1) Remark: The material CoCr20Ni15Mo with the material number 2.4711 is known as UNS R 30003 in the USA. It is a hardenable, creep-resistant spring alloy with an operating temperature of up to 320 °C. It possesses a very good corrosion-resistance and very favourable fatigue properties, and it is hard to machine it in a metal-removing way. The material is weldable and cold-formable.
