    Material grade and standard properties

    Samim Rahman

      Hello, everyone! Have a nice day! Can anyone help on These material grades meaning and Their standard properties value.
      A2-70, A2-80, 200HV, 200HV HDG, 200HV St, 8.8 St, 200HV Zn, 8.8HDG.

       

      Thanks

            HDG = Hot Dipped Galvanized

            8.8 = Metric bolt strength

            A2-70 = stainless steel

             

            These all seem to be fasteners/washers, etc. Ask your supplier for the material properties. If you are just wanting material properties for FEA then just use steel/stainless properties for E & nu.

              Hello everyone, Thanks for your knowledge to share. I've  searched about the Hot dip Galvanized. It is a coating process of Zinc material on base material. now my my question is that what is impact of this coating to the property of base material. Are there any change happened due to coating. e.g any change of property value  (Modulus of Elasticity, Poissons's ratio,shear modulus, mass density, Tensile strength, Yield strength, Compressive strength, Thermal expansion coefficient, Thermal conductivity, Specific heat, Material damping ratio, etc) ? if it change then what are standard values of these? your contribution will be much helpful.
