Markforged Metal X Gets First Material Data with 17-4 PH Stainless Steel

metal print

Markforged has released its first material specifications for the upcoming Metal X 3D printer, in the form of preliminary data for 17-4 PH stainless steel, a martensitic precipitation-hardening stainless steel.

Renowned for its high-strength, corrosion resistance and machinability, 17-4 PH stainless steel is widely used to manufacture mechanical end-use parts and components that require exceptional hardness and a resistance to temperatures exceeding 316°C. One of the benefits of 3D printing with 17-4 PH stainless steel is that the hardness and toughness of this metal can be manipulated during the heat treatment process.

Markforged’s preliminary data for 17-4 PH stainless steel shows an ultimate tensile strength of 1050 MPa when sintered with the Markforged Sinter-1 and when sintered by an MIM facility, rising to 1090 MPa when sintered by the Wrought 17-2 PH SS. The tensile modulus is listed at 125 GPa, while the hardness is listed at 35 HRC when sintered with the Markforged Sinter-1 and MF MP. These ratings put Markforged’s 17-4 PH stainless steel on par with the norm.

The above mechanical properties were tested and verified internally by Markforged. However, they are preliminary findings only. 3rd party data will be added to these findings in the future.
