At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM A1082/A1082M. ASTM A1082/A1082M covers high-strength precipitation-hardening and ferritic-austenitic (duplex/super-duplex) stainless steel bolting – bolts, screws, stud bolts, threaded rod, and nuts – for special-purpose and corrosive applications such as pressure vessels and flanged joints. It combines high strength with the corrosion resistance of duplex and PH stainless grades.
