What is ASTM A860 WPHY 46?
ASTM A860 covers a specification on wrought high strength ferritic alloy steel buttwelding fittings for high-pressure gas and oil transmission systems. The abbreviation “WPHY” means wrought pipe high yield while “46” means minimum yield strength of 46,000 psi (46,000 psi).
ASTM A860 WPHY 46 High Yield Buttweld Fittings offer greater strength-to-weight ratio compared to traditional carbon steel fittings and enables engineers to create an effective piping system while providing sufficient strength at high operating pressure.
These materials are optimal for the construction of pipeline facilities where safety, reliability and extended lifespan are of major concern.

Highlights of ASTM A860 WPHY46 High Yield Buttweld Fittings
- Superior Mechanical Strength: ASTM A860 WPHY 46 fittings possess substantially higher yield strength compared to carbon steel fittings, making them well-suited for high pressure systems.
- Excellent Weldability: These fittings are readily welded by common welding processes producing reliable, leak-free pipeline connections.
- Superior Toughness: The material is a very tough material at many different temperatures and offers a decreased possibility of brittle fracture in critical service conditions.
- Extended Service Life: The high strength to pressure fluctuation and mechanical stress factors helps ensure a long service life and decreased costs of operation and maintenance.
- Cost-Effective Pipeline Solution: Due to its inherent strength, an engineer may optimize system design by using high yield strength buttweld fittings to achieve desired performance and safety in a most economical and responsible way.
