Standard Rivet Material
Special grades of steel wire - forged, hardened and tempered to provide optimum joint properties in the full range of application materials.
Special Rivet Materials
Austenitic stainless steel – used for joining ductile stainless steel sheets.
Martensitic stainless steel– for tougher materials that cannot be joined with rivets made from austenitic stainless steel.
Copper – special applications such as copper, brass and plastics.
Aluminium – suitable for joining soft grades of aluminium.
Rivet Hardness
Rivets are produced in a range of hardness levels to match the piercing requirement for different material grades. In general terms the rivet hardness increases with material thickness and/or hardness. Henrob should always be contacted to establish the correct rivet hardness and geometry for the application.
