The DURIMPHY steel is used in a large number of applications in various industrial segments. For example, components for the aerospace industry, as well as parts for the micromechanical engineering and the watch making industry. Hoeever its low to fair corrosion resistance is a limiting factor.
The DURIMPHY is a clean double vacuum VIM-VAR melted low C precipitation hardening martensitic steel. In the 830°C annealed / uenched condition, it exhibits a soft martensitic microstructure amenable to plastic deformation up to very high reductions and to machining. Its age hardening is preferably made at 480°C. The cumulative contributions of cold deformation and age hardening permit to obtain reproducibly hardness values of HRc 52 – 55. The precipitation hardening causes neither the formation of internal stresses, nor dimensional changes. In the hardened condition this steel shows high UTS / Rm and YS0.2 / R0.2 strengths, as well as fatigue resistance, and notch impact resistance. This steel does not have a ductile-brittle transition temperature down to the coldest cryogenic temperatures. It can continuously be used up to max. 400°C. It can easily be welded and brazed.
