At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A182. ASTM A182/A182M covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves and parts for high-temperature service. Grades span low-alloy (F1-F91), martensitic (F6), austenitic stainless (F304, F316, F321, F347) and ferritic-austenitic duplex (F51, F53, F55/F60). The ASME equivalent, SA-182, is the ASME BPVC Section II adoption with essentially identical content.
