ASTM A350 Specification
ASTM A350 is a standard material specification for carbon and low alloy steel forgings, requiring notch toughness testing for piping components. This includes forged flanges, fittings, valves and similar forged and machined parts. This specification covers requirements such as chemical composition, mechanical properties and impact test for notch toughness. Ferrobend stocks, manufactures and supplies forgings, flanges, pipe fittings, valves and similar piping components in ASTM A350 Specification.
