Applications

  • Automotive valves - can withstand gas temperatures of upto 1500°F for a minimum of 50,000 miles.
  • Fastener galling - capable of frequent assembly and disassembly, allowing more use of the fastener before the threads are torn up, also helps to eliminate corroded or frozen fasteners.
  • Pins - Used in roller prosthetics & chains to ensure a better fit of parts (closer tolerance, non-lubricated) and longer lasting.
  • Marine shafts - better corrosion than types 304 and 316, with double the yield strength.
  • Pin and hanger expansion joints for bridges - better corrosion, galling-resistance, low temperature toughness, & high charpy values at sub-zero temps compared to the A36 and A588 carbon steels commonly used.
