Bilal Nickel Alloys, headquartered in Safat, Kuwait, is a trusted manufacturer and supplier of Duplex Steel 2205 Bolts, engineered for exceptional strength, corrosion resistance, and long-term durability. These bolts are precision-engineered to provide secure, reliable fastening in high-pressure, chemically aggressive, and marine environments. Leveraging decades of expertise in duplex stainless steels, Bilal Nickel Alloys ensures that every 2205 bolt meets stringent quality standards, combining mechanical performance with chemical stability. Their commitment to engineering excellence and customer satisfaction makes these bolts a preferred choice for industries requiring robust, high-performance, and corrosion-resistant fasteners for critical industrial and offshore applications.
Duplex Steel 2205 Bolts 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, these bolts maintain structural integrity under high-pressure and high-temperature conditions. Their robust microstructure ensures long-term durability, dimensional stability, and chemical resistance, making 2205 bolts ideal for critical industrial applications where both mechanical strength and corrosion protection are essential.
