GKN Additive reports that it has developed two alloys similar to DP600 steel for use in additive manufacturing (AM).
DP600 is a low alloy dual-phase steel used the automotive industry, the company said.
The new metal powder materials, dual phase low alloy (DPLA) and free sintering low alloy (FSLA) reportedly meet similar requirements for mechanical properties as DP600 (HCT600X/C), such as higher ultimate tensile strength (UTS) and low yield strength (YS) to UTS ratio. They can be used in laser powder bed fusion (DPLA) and binder jetting (FSLA).
GKN says that the alloys are also specialized for additive manufacturing with regard to spreadability, laser absorption (laser AM) and sinterability (binder jetting).
‘Traditional DP600 offers specific standardized mechanical properties achieved by heat treatment,’ said Christopher Schaak, technology manager for binder jetting. ‘The dual-phase steel AM materials developed by GKN Additive on the other hand are very flexible in their characteristics, as their mechanical properties can be tuned more widely by the heat treatment after the laser or binder jetting process.’
