At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A105. ASTM A105/A105M covers forged carbon steel piping components – flanges, fittings, valves, and similar parts – for ambient- and higher-temperature service in pressure systems, up to a forging mass of 4540 kg (10,000 lb). It is one of the most widely used carbon steel flange and forged-fitting standards. A single strength grade applies.
