At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ASTM B805. CORRECTION: ASTM B805 covers PRECIPITATION-HARDENING NICKEL ALLOYS in bar and wire form (not ‘copper-nickel wire’). It supplies high-strength, corrosion-resistant age-hardened nickel-alloy bar/wire for bolting, studs and springs in sour-gas, marine and downhole service.
