Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Is Plywood stronger than Stainless 303? Stainless 303 is stronger: its yield strength is 275 MPa against tensile strength 41.4 MPa for Plywood (6.65x).
Which is stiffer, Plywood or Stainless 303? Stainless 303 is stiffer: Young's modulus 200 GPa against 7.45 GPa for Plywood, so the same part in Stainless 303 deflects less under the same load.
Which conducts heat better, Plywood or Stainless 303? Stainless 303 conducts heat better: 15 W/m·K against 0.12 W/m·K for Plywood.
Which expands less with temperature? Plywood expands less: 3.8 µm/m·K against 16 µm/m·K for Stainless 303.
