Frequently Asked Questions
ASTM A694 F52 Flanges are forged steel piping components designed for high-pressure oil, gas, and pipeline transmission applications. They have a minimum yield strength of 52 ksi (360 MPa).
Common tests include chemical analysis, tensile testing, hardness testing, dimensional inspection, and nondestructive examination when required by the applicable specification or purchase order.
ASTM A694 F52 Flanges may be used in sour gas service if the material condition, hardness, manufacturing controls, and testing meet applicable sour-service requirements, such as NACE MR0175/ISO 15156.
A694 F52 has a minimum yield strength of 360 MPa (52 ksi) at 0.2% offset, minimum tensile strength of 455 MPa (66 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.
F52 carries a 360 MPa minimum yield strength, between F50 (345 MPa) and F56 (385 MPa), positioning it in the mid-range of the high-yield A694 family.
