Questions Is Plywood stronger than Stainless 304? Stainless 304 is stronger: its yield strength is 241 MPa against tensile strength 41.4 MPa for Plywood (5.83x).
Which is stiffer, Plywood or Stainless 304? Stainless 304 is stiffer: Young's modulus 193 GPa against 7.45 GPa for Plywood, so the same part in Stainless 304 deflects less under the same load.
Which conducts heat better, Plywood or Stainless 304? Stainless 304 conducts heat better: 16.2 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 16.9 µm/m·K for Stainless 304.
