GKN Sinter Metals reports in its blog that it has developed 20MnCr5, a new low carbon alloy steel intended for metal additive manufacturing (AM).
The case-hardened material has will be used to build prototypes for gears and has a high strength with ductility, high fatigue strength, wear resistance through case hardening and inherent toughness.
‘We can now manufacture parts made completely of 20MnCr5 and offer hybrid production, meaning we are able to combine different manufacturing techniques with Metal AM using this new material,’ said Simon Höges, manager additive manufacturing. ‘As it can be combined with all weldable materials, the potential this creates in the aftermarket sector using AM particularly regarding the production of low volume spare parts is immense.’
