Luke Steel, a reputable manufacturer and supplier of Alloy Steel Grade 9 Foils with headquarters in Houston, Houstan, provides premium alloy materials for applications requiring high temperatures and high stresses. Grade 9 foils are designed to satisfy demanding industrial specifications and provide exceptional mechanical strength, resistance to corrosion, and thermal stability. These precision foils are perfect for the high-performance engineering, chemical processing, power generation, and aerospace industries. Luke Steel offers customised solutions to satisfy the demands of demanding environments while guaranteeing consistent quality, dimensional accuracy, and quick delivery. Luke Steel is your go-to supplier for cutting-edge alloy steel products because of its solid reputation for dependability.
Chromium (4–6%), molybdenum (0.4–0.6%), and vanadium (0.25–0.35%) make up Alloy Steel Grade 9 Foils. They also contain carbon (0.15–0.25%), manganese (0.50–0.80%), and trace amounts of silicon, phosphorus, and sulphur. These foils have a minimum yield strength of about 60,000 psi and a tensile strength of roughly 90,000 to 100,000 psi. Usually heat-treated for improved mechanical properties, Grade 9 foils are renowned for their superior oxidation resistance, high creep strength, and toughness at high temperatures. They have outstanding formability and dimensional consistency, making them perfect for harsh industrial use due to their stable alloying elements and fine structure.
