Spring Steel

SUP9A is a kind of hot-rolled alloy spring steel well suited for fabrication that requires shaping by blanking, bending, drawing, extrusion and swaging. It allows for closer dimensional tolerances and improved finishing.

General Applications:-
  • Highly stressed
  • quenched and tempered springs
  • hand tools
  • larger diameter coiled spring sand rock drilling studs in vehicle and tractor industries
