Titanium forged fittings are primarily composed of pure titanium or titanium alloys, typically including small percentages of elements like aluminum, vanadium, molybdenum, and iron. For example, Grade 5 titanium (Ti-6Al-4V) contains 6% aluminum and 4% vanadium, enhancing strength and corrosion resistance. Titanium forged fittings are renowned for their exceptional strength-to-weight ratio, with tensile strength ranging from 300 MPa to over 1000 MPa, depending on the grade. They exhibit excellent corrosion resistance, superior ductility, and high fatigue strength, making them ideal for demanding environments in aerospace, chemical processing, and marine industries.
The Super Duplex Steel Pipe Fittings we offer are made up of a unique blend of materials, including chromium (24–26%), nickel (6–8%), molybdenum (3–5%), nitrogen, and just the right amount of iron. This special composition boosts their resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these fittings deliver high tensile strength (usually over 750 MPa), excellent yield strength, and impressive impact toughness, even in freezing temperatures. Their dual-phase microstructure, combining ferritic and austenitic phases, ensures superior structural integrity, making them perfect for the demanding industrial environments found in Cape Town.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Titanium Forged Fittings from Khuliso Fittings offer exceptional corrosion resistance, especially in seawater and harsh environments. They are known for their high strength, durability, and resistance to pitting and crevice corrosion, ensuring long-lasting performance.
