Questions

Mechanical

Is DMLS 17-4PH Stainless Steel stronger than Stainless Steel 17-4PH?

Stainless Steel 17-4PH is stronger: its yield strength is 1,275 MPa against 861 MPa for DMLS 17-4PH Stainless Steel (48%).

Which is lighter, DMLS 17-4PH Stainless Steel or Stainless Steel 17-4PH?

DMLS 17-4PH Stainless Steel is lighter: 7,790 kg/m³ against 7,800 kg/m³ for Stainless Steel 17-4PH.

Which is stiffer, DMLS 17-4PH Stainless Steel or Stainless Steel 17-4PH?

DMLS 17-4PH Stainless Steel is stiffer: Young's modulus 197 GPa against 197 GPa for Stainless Steel 17-4PH, so the same part in DMLS 17-4PH Stainless Steel deflects less under the same load.

Which is lighter for the same job, DMLS 17-4PH Stainless Steel or Stainless Steel 17-4PH?

For the same stiffness or strength: Stainless Steel 17-4PH is lighter for a strong rod or tie, strong beam, strong panel or plate.

Part that must beDMLS 17-4PH Stainless SteelStainless Steel 17-4PH
Stiff rod or tie (tension)about equalabout equal
Stiff beam (bending)about equalabout equal
Stiff panel or plateabout equalabout equal
Strong rod or tie48% heavierlighter
Strong beam30% heavierlighter
Strong panel or plate22% heavierlighter

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).

Which is more ductile, DMLS 17-4PH Stainless Steel or Stainless Steel 17-4PH?

DMLS 17-4PH Stainless Steel stretches further before it breaks: 19.9% elongation at break against 9% for Stainless Steel 17-4PH.

Thermal
