Duplex Steel Anchor Fasteners Manufacturer in India

Duplex Steel Anchor Fasteners are highly durable and corrosion-resistant fasteners used for secure anchoring in extreme environments. Manufactured from Duplex (UNS S31803, S32205) and Super Duplex (UNS S32750, S32760) Stainless Steel, these fasteners offer high strength, excellent resistance to pitting and crevice corrosion, and superior mechanical properties.

They are ideal for industries such as marine, oil & gas, chemical processing, desalination plants, and heavy engineering where standard stainless steel fails under harsh conditions.

High-Quality Duplex Steel Anchor Fasteners

Duplex Steel Anchor Fasteners provide twice the strength of conventional stainless steel while maintaining excellent weldability and toughness. Their high chromium, molybdenum, and nitrogen content ensures superior resistance to corrosion, stress cracking, and extreme temperatures.

Types of Duplex Steel Anchor Fasteners
