ASTM A181 Gr 1 Carbon Steel Forgings – Ideal for flanges, fittings & valves with excellent weldability, strength & machinability for general
ASTM A181 Grade 1 is a carbon steel forging material used for general‑purpose industrial components such as flanges, fittings, valves, and other pressure‑containing parts. It offers excellent weldability and formability, good machinability, and moderate tensile and yield strength suitable for service at ambient to moderately elevated temperatures.
Manufactured through open‑die or closed‑die forging and heat‑treated (normalized/annealed), ASTM A181 Gr 1 components are dimensionally stable and reliable for fabrication into products like weld neck, slip‑on, blind, socket weld, and threaded flanges, as well as forged fittings such as elbows, tees, couplings, reducers, and caps.
