Bilal Nickel Alloys, based in Safat, Kuwait, is a trusted manufacturer and supplier of Duplex Steel 2205 Stud Bolts, designed for exceptional strength, corrosion resistance, and long-term reliability. These stud bolts are engineered for demanding industrial applications, ensuring secure and leak-free connections in high-pressure, chemically aggressive, and marine environments. With decades of expertise in duplex stainless steels, Bilal Nickel Alloys guarantees that every 2205 stud bolt meets stringent quality standards, combining mechanical integrity with corrosion protection. Their commitment to precision engineering and customer satisfaction makes these stud bolts a preferred choice for industries requiring robust, high-performance, and corrosion-resistant fastening solutions.
Duplex Steel 2205 Stud 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 delivers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, while offering high tensile strength, hardness, and ductility. Mechanically, 2205 stud bolts maintain structural integrity under high-pressure and high-temperature conditions. Their robust microstructure ensures long-term durability, dimensional stability, and chemical resistance, making them ideal for critical industrial applications that demand both mechanical strength and protection against aggressive environments.
