As well as having a strong focus on product consistency, Sandvik Osprey has sought over the years to understand more of its customers’ experience of its products through characterisation and customisation of its growing product range. By controlling the alloying, atomising and sizing processes, powder producers can subtly influence the compounding, moulding and sintering behavior in customers’ processes delivering various positive outcomes. In this retrospective, examples are given in case studies on fluidity, strength and surface finish in 17-4PH, high temperature stability in HK30 turbocharger alloy, improved processing windows and tolerance control in tool steels and martensitic stainless steels and the exceptional mechanical properties developed in Ni base superalloys for auto and aero applications. While primarily relating to MIM, the benefits described are potentially applicable in emerging binder jet technologies where additional emphasis is put on powder flow and packing density.
