Questions
Is Brick stronger than DMLS 17-4PH Stainless Steel?
DMLS 17-4PH Stainless Steel is stronger: its yield strength is 861 MPa against tensile strength 5.1 MPa for Brick (169x).
Which is lighter, Brick or DMLS 17-4PH Stainless Steel?
Brick is lighter: 2,082 kg/m³ against 7,790 kg/m³ for DMLS 17-4PH Stainless Steel.
Which is lighter for the same job, Brick or DMLS 17-4PH Stainless Steel?
For the same stiffness or strength: DMLS 17-4PH Stainless Steel is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brick | DMLS 17-4PH Stainless Steel |
|---|---|---|
| Strong rod or tie | 45.1x heavier | lighter |
| Strong beam | 8.16x heavier | lighter |
| Strong panel or plate | 3.47x heavier | lighter |
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).
