Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.

DMLS 17-4PH Stainless Steel and DMLS 316L Stainless Steel are 3D printed: their properties depend on build direction and print settings; these are typical values.

Questions

Mechanical

Is DMLS 17-4PH Stainless Steel stronger than DMLS 316L Stainless Steel?

DMLS 17-4PH Stainless Steel is stronger: its yield strength is 861 MPa against 530 MPa for DMLS 316L Stainless Steel (1.62x).

Which is lighter, DMLS 17-4PH Stainless Steel or DMLS 316L Stainless Steel?

DMLS 17-4PH Stainless Steel is lighter: 7,790 kg/m³ against 7,900 kg/m³ for DMLS 316L Stainless Steel.

Which is stiffer, DMLS 17-4PH Stainless Steel or DMLS 316L Stainless Steel?

DMLS 17-4PH Stainless Steel is stiffer: Young's modulus 197 GPa against 185 GPa for DMLS 316L Stainless Steel, 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 DMLS 316L Stainless Steel?

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

Part that must beDMLS 17-4PH Stainless SteelDMLS 316L Stainless Steel
Stiff rod or tie (tension)lighter8% heavier
Stiff beam (bending)lighter5% heavier
Stiff panel or platelighter4% heavier
Strong rod or tielighter1.65x heavier
Strong beamlighter40% heavier
Strong panel or platelighter29% heavier

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 DMLS 316L Stainless Steel?

DMLS 316L Stainless Steel stretches further before it breaks: 40% elongation at break against 19.9% for DMLS 17-4PH Stainless Steel.

Thermal

Which conducts heat better, DMLS 17-4PH Stainless Steel or DMLS 316L Stainless Steel?

DMLS 17-4PH Stainless Steel conducts heat better: 17.9 W/m·K against 16.2 W/m·K for DMLS 316L Stainless Steel.

Which expands less with temperature?

DMLS 17-4PH Stainless Steel expands less: 10.4 µm/m·K against 15.7 µm/m·K for DMLS 316L Stainless Steel.
