• Austenitic (Chrome Nickel)
  • Good Cold Working
  • Good Elongation in Full Hard Condition
  • Good Fatigue Life
  • High Strength to Weight Ratio
  • Work Hardens Readily - so is in demand in harder tempers
  • Not Heat-treatable for Hardening Purposes
  • Non-magnetic in Annealed Condition
  • Slightly Magnetic in Work-hardened Condition
  • Good Heat and Corrosion Resistance
  • Welds Easily
  • Solution Annealed by Cooling Rapidly from 2000°F in Air or Water.
