Luke Steel provides high-strength F80 Forged Carbon Steel Fittings, which are made in Houston, Houstan, for severe service conditions. Being a top-class supplier, we deal in fittings designed to perform well under extreme pressure and temperature conditions. These forged fittings are precision-made and quality-tested to adhere to international specifications. Our F80 fittings are extensively used in energy, oil & gas, and chemical sectors and provide unbeatable strength and leak-tightness. Luke Steel‘s insistence on superior quality, innovation, and customer satisfaction makes us your go-to partner for carbon steel solutions in mission-critical industrial applications.
Carbon Steel F80 Forged Fittings consist of approximately 0.28% carbon, 1.50% manganese, and trace amounts of phosphorus and sulfur, all balanced to create utmost strength. These fittings have a minimum yield strength of 550 MPa and tensile strength exceeding 620 MPa, making them appropriate for ultra-high pressure conditions. F80 is heat-treated for enhanced impact toughness, hardness, and fatigue resistance. The material has excellent weldability and formability, suited for intricate pipeline systems. Its mechanical and chemical characteristics provide durability, structural integrity, and reliable performance in the most strenuous industrial applications.
