At Ananka Fasteners Pvt Ltd, we manufacture and supply fasteners certified to ISO 3506-5. ISO 3506-5:2022 – Mechanical properties of corrosion-resistant stainless steel fasteners – Part 5: Special fasteners (also including fasteners from nickel alloys) for high-temperature applications. Covers high-alloy austenitic stainless and nickel-base alloy bolts, screws, studs and nuts for elevated-temperature service beyond the scope of ISO 3506-1/-2. (Input ‘Bolting – Special Purpose Alloy’ refined to high-temperature special/nickel-alloy fasteners.)
