ASTM A694 F52 WNRTJ FLANGES ASME B16.5 B16.47A

ASTM A694 is the standard specification for carbon and alloy steel forgings for pipe flanges, fittings, valves, and parts for high-pressure transmission service which are manufactured for use with high-strength transmission-service pipe.

ASTM A694 F52 is one of the popular high yield steel grades under ASTM A694 specification.

The same as API 5L grade X52 steel line pipes and ASTM A860 WPHY52,ASTM A694 F52 has the 415 mpa Tensile Strength

A694 F52 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 ℃].
