ASTM A694 F50 Forged Steel Flanges are forged steel pipe parts that are utilized in the transmission systems where reliability in strength and pressure resistance are crucial. Grade F50 is produced to meet ASTM A694/A694M material requirements and is intended for use in aforementioned specified oil and gas pipelines, petrochemical plants and industrial distribution systems that require a minimum yield of 50 ksi (345 MPa). Based on the project needs and applicable dimensional standards, the flanges can be provided in various configurations, sizes, pressure classes and facing arrangements. Tests such as chemical composition verification, mechanical testing and dimensional inspection are used to assist in ensuring the required material grade and purchase order is met. Solitaire Overseas is a trusted manufacturer and supplier of ASTM A694 F50 Flanges in India, and we provide delivery to domestic and overseas industrial customers.

A694 F50 Figure 8 Flanges DistributorA694 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.
