ASTM A694 / A694M

ASTM A694 is a material specification for Carbon and Alloy Steel forged products such as flanges, pipe fittings, valve component, rings, round bars, piping components and many other forging parts, used for boilers, pressure vessels, associated equipment and high transmission services. ASTM A694 covers nine grades under various classes of carbon and alloy steel. ASTM A694 product can be ordered either to dimensions specified by the buyer or to dimensional standards such as ANSI, ASME, API or MSS.
