Questions
Is Brick stronger than Stainless 303?
Stainless 303 is stronger: its yield strength is 275 MPa against tensile strength 5.1 MPa for Brick (53.9x).
Which is lighter, Brick or Stainless 303?
Brick is lighter: 2,082 kg/m³ against 7,900 kg/m³ for Stainless 303.
Which is lighter for the same job, Brick or Stainless 303?
For the same stiffness or strength: Stainless 303 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brick | Stainless 303 |
|---|---|---|
| Strong rod or tie | 14.2x heavier | lighter |
| Strong beam | 3.76x heavier | lighter |
| Strong panel or plate | 1.94x 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 303?
Stainless 303 conducts heat better: 15 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 16 µm/m·K for Stainless 303.
