ASTM A694 FLANGES SPECIFICATION
ASTM A694-A694M is the standard specification for carbon steel and alloy steel forgings including pipe flanges, fittings, valves and other piping components for high-pressure transmission service. The material can be categorized into several grades: ASTM A 694 Grade F42, F52, F56, F60, F65 and F70. They are widely used in high-pressure oil and gas transmission pipelines as well as wellhead and manifold devices.
ASTM A694 F65 Flange,forged flanges can be furnished in accordance with MSS SP 44, ASME B16.47(both Series A and Series B) and ASME B16.5,API 6A 6BX Flange

A694 F65 Flange Heat treatment
All forgings should be heat treated. The heat treatment of carbon steel and high-strength low-alloy steel should be normalized, normalized or tempered or quenched and tempered. The heat treatment of alloy steel is aging treatment with quenching and precipitation or aging treatment with quenching and precipitation.
Tempering temperature shall be at least 1000 ℉ [540 ℃], precipitation heat treatment of alloy steel shall be in range from 1000 to 1225 ℉ [540 ℃ to 665 ℃].
