At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A181. ASTM A181/A181M covers forged carbon steel components for general-purpose piping – nonstandard as-forged fittings, valve components, and parts – for ambient and higher-temperature service, up to a forging mass of 4540 kg (10,000 lb). Two strength classes, 60 and 70, are provided. It is a lower-cost general-service counterpart to ASTM A105.
