Bilal Nickel Alloys, based in Safat, Kuwait, is a trusted manufacturer and supplier of Duplex Steel 2205 Fasteners, engineered for exceptional strength, durability, and corrosion resistance. Designed for demanding industrial environments, these fasteners provide secure, reliable connections in high-pressure, marine, and chemically aggressive applications. Leveraging extensive expertise in duplex stainless steels, Bilal Nickel Alloys ensures that every 2205 fastener meets strict quality standards, combining mechanical performance with long-term reliability. Their commitment to precision engineering and customer satisfaction makes these fasteners a preferred choice for industries requiring robust, high-strength, and corrosion-resistant fastening solutions for critical infrastructure and equipment.
Duplex Steel 2205 Fasteners are composed of iron, chromium (~22%), nickel (~5–6%), molybdenum (~3%), and nitrogen, forming a balanced duplex microstructure of ferrite and austenite. This composition provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, while delivering high tensile strength, hardness, and ductility. Mechanically, 2205 fasteners maintain structural integrity under high-pressure and elevated-temperature conditions. Their robust microstructure ensures long-term durability, dimensional stability, and chemical resistance, making these fasteners ideal for critical industrial applications where both mechanical strength and corrosion protection are essential.
