ASTM A694 grade F65 is a low alloy steel often selected for its high yield strength combined with excellent low temperature toughness and weldability.
ASTM A694 F46 is a specification developed by ASTM International (formerly known as the American Society for Testing and Materials) that covers carbon and alloy steel forgings for pipe flanges, fittings, valves, and other high-pressure and high-temperature service Components. Specifically, ASTM A694 F46 is categorized as a low alloy steel with enhanced mechanical properties suitable for applications in the oil, gas, petrochemical, and power generation industries.
ASTM A694 F46 Flanges is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.ASTM A694 F46 Standard Specification for Carbon and Alloy Steel Forgings for Pipe Flanges, Fittings, Valves, and Parts for High-Pressure Transmission Service. Several grades of material, based on minimum yield strength requirements, are covered Materials adhere to testing and tensile property requirements as well.
