Questions
Is Brick stronger than Stainless 17-4PH?
Stainless 17-4PH is stronger: its yield strength is 1,275 MPa against tensile strength 5.1 MPa for Brick (250x).
Which is lighter, Brick or Stainless 17-4PH?
Brick is lighter: 2,082 kg/m³ against 7,800 kg/m³ for Stainless 17-4PH.
Which is lighter for the same job, Brick or Stainless 17-4PH?
For the same stiffness or strength: Stainless 17-4PH is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brick | Stainless 17-4PH |
|---|---|---|
| Strong rod or tie | 66.7x heavier | lighter |
| Strong beam | 10.6x heavier | lighter |
| Strong panel or plate | 4.22x 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).
Which conducts heat better, Brick or Stainless 17-4PH?
Stainless 17-4PH conducts heat better: 17.9 W/m·K against 1.02 W/m·K for Brick.
Which expands less with temperature?
Brick expands less: 7.2 µm/m·K against 10.8 µm/m·K for Stainless 17-4PH.
