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 Steel A992? Steel A992 is stronger: its yield strength is 385 MPa against tensile strength 41.4 MPa for Plywood (9.31x).
Which is stiffer, Plywood or Steel A992? Steel A992 is stiffer: Young's modulus 200 GPa against 7.45 GPa for Plywood, so the same part in Steel A992 deflects less under the same load.
Which conducts heat better, Plywood or Steel A992? Steel A992 conducts heat better: 48 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 12 µm/m·K for Steel A992.
