What is ASTM A860 WPHY 65?

ASTM A860 Gr WPHY 65 is a standard for wrought high-strength ferritic alloy steel butt weld fittings for high pressure gas and oil transmission duty. The “WPHY” marking is for “Wrought Pipe High Yield” and “65” is the minimum yield strength of 65 ksi.

ASTM A860 WPHY 65 Buttweld Pipe Fittings are widely selected for applications requiring:

  • High tensile strength
  • Superior toughness
  • Excellent weldability
  • Resistance to stress and pressure
  • Reliable low-temperature performance

These fittings are commonly associated with API 5L X65 pipeline systems due to similar mechanical properties and pressure-handling capabilities.
