High-alloy precision steels are virtually indispensable components in precision instrumentation. Thanks to the precise calculation of the components used, they possess unparalleled characteristics with respect to strength, corrosion resistance and electrical conductivity. These nickel-based alloys were such an important discovery in terms of technological progress that in 1920 a Swiss scientist was awarded the Nobel Prize in Physics for the creation of the Invar alloy.
