ASTM A105 is the most widely used standard specification for forged carbon steel piping components, including flanges, fittings, and valves, designed for ambient- and higher-temperature service in pressure systems. These components are essential in industries like oil and gas, petrochemicals, and power generation due to their high strength and durability. Material: Forged carbon steel (killed steel). Service Temp: −20°F to 800°F (−29°C to 427°C).
Common in 150# to 2500# (Class 150-300 often "As Forged," higher classes usually normalized). CARBON STEEL ASTM A105 FLANGE
