ASTM A860 WPHY60 Elbow 90 Deg LR | High Strength Butt Weld Pipe Fittings
ASTM A860 WPHY60 elbows are high-strength carbon steel butt weld fittings designed for high-pressure and low-temperature pipeline systems. Manufactured in accordance with ASTM A860 and ASME B16.9, they provide high yield strength (60 ksi), excellent toughness, and reliable performance in oil & gas transmission and offshore applications.
What is ASTM A860 WPHY60?
ASTM A860 is a specification for high-strength ferritic steel butt weld fittings used in demanding pipeline systems.
WPHY60 Meaning:
- WP = Wrought Pipe fitting
- HY = High Yield strength
- 60 = Minimum yield strength (60 ksi / 415 MPa)
Product Range
We supply a full range of ASTM A860 WPHY60 fittings:
- 90° Long Radius Elbow

Starting Material for WPHY60 Fittings
ASTM A860 WPHY60 elbows are manufactured from high-strength carbon steel starting materials, typically:
- ASTM A694 F60 forgings
- API 5L X60 pipe or plate
- Controlled carbon steel billets
Material Requirements:
- Controlled chemical composition
- Low carbon equivalent (CE)
- Heat treated (normalizing or Q&T)
Ensures required strength and toughness in final fittings
Pipeline System Matching
A correct WPHY60 system typically includes:
- Pipe: API 5L X60
- Fitting: ASTM A860 WPHY60
- Flange: ASTM A694 F60
- Bolting: ASTM A193 B7 / ASTM A320 L7
Ensures:
✔ Strength consistency
