Frequently Asked Questions

A694 F50 has a minimum yield strength of 345 MPa (50 ksi), minimum tensile strength of 440 MPa (64 ksi), and minimum elongation of 20% in 2 inches.

ASTM A694 covers material requirements only. Flange dimensions, facing, and pressure class follow ASME B16.5 up to NPS 24, or ASME B16.47 for larger sizes.

F50 carries a 345 MPa minimum yield strength, between F48 (330 MPa) and F56 (385 MPa), making it a mid-range option in the high-yield A694 family.

Weld neck, slip-on, blind, lap joint, socket weld, and threaded flanges are manufactured in A694 F50 to the required pressure class and facing.

Cross-country crude oil and gas pipelines, offshore and subsea systems, petrochemical and refinery projects, and power plant piping requiring elevated yield strength.
