Boikanyo Metals is a reliable manufacturer and supplier of Inconel 718 Fasteners, proudly based in Cape Town, South Africa. They provide top-notch materials designed for high-temperature, corrosion-resistant, and critical industrial applications. Inconel 718, a nickel-chromium alloy, is celebrated for its outstanding mechanical strength, resistance to oxidation, and stability even at elevated temperatures. This makes it a perfect fit for industries like aerospace, power generation, chemical processing, and petrochemicals. Boikanyo’s Inconel 718 Fasteners are meticulously engineered to meet international standards, guaranteeing dependable performance, durability, and a long service life.
These fasteners primarily consist of nickel (50–55%), chromium (17–21%), iron (the balance), along with trace amounts of molybdenum, niobium, titanium, and aluminum. This unique blend offers remarkable resistance to creep, fatigue, and stress corrosion cracking, all while maintaining high tensile strength and dimensional stability in extreme temperatures. Plus, they provide solid corrosion resistance in harsh chemical and marine environments.
