Sandvik 11R51 Spring Wire
Categories: Metal; Ferrous Metal; Special-Purpose Steel

Material Notes: Compared with standard grades Sandvik 12R10/gusab T302, Sandvik 11R51 offers:
  • higher tensile strength and tempering effect
  • higher relaxation resistance, especially at elevated temperatures
  • higher fatigue strength
  • better corrosion resistance, through the addition of molybdenum
  • Service temperature: -200 to 300°C (-330 to 570°F)
