A ferritic alloy steel comprising chromium (1.0–1.5%), molybdenum (0.44–0.65%), carbon (0.05–0.15%), manganese (0.30–0.60%), phosphorus (≤0.025%), sulphur (≤0.025%), and silicon (≤0.50%) is used to make Alloy Steel Grade 11 Foils. With a tensile strength range of 60,000–85,000 psi and a yield strength of roughly 30,000–45,000 psi, these foils are made to offer high strength and exceptional creep resistance at high temperatures. Molybdenum improves resistance to corrosion and oxidation under high heat conditions. Because of its excellent ductility, thermal stability, and dependable weldability, alloy steel grade 11 is appropriate for precision applications in high-temperature settings.
Alloy Steel Grade 11 Foils contain almost entirely chromium, molybdenum, and carbon, with minute proportions of silicon, manganese, and phosphorus. This content provides corrosion resistance, heat resistance, and mechanical strength. The foils will have tensile strengths of about 415–585 MPa and yield strength of about 205 MPa, with satisfactory elongation characteristics. Their high creep resistance and stability against oxidation in high-temperature conditions make them particularly useful in challenging conditions. The mechanical properties are such that Alloy Steel Grade 11 Foils will be able to withstand structural integrity and performance in the face of mechanical stress and thermal exposure.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Because of their resistance to high temperatures and corrosive conditions, alloy steel grade 11 foils are extensively utilised in the petrochemical, oil and gas, and power generation sectors. Heat exchanger fins, boiler tube wraps, insulation barriers, and pressure vessel and heater linings are examples of common uses. In steam and combustion systems, these foils can also be used for gaskets, sealing strips, and thin-wall manufactured parts. Grade 11 is perfect for precision components subjected to prolonged heat exposure because of its exceptional formability and resistance to thermal fatigue. In both static and cyclic thermal conditions, the foils provide long-lasting performance and dimensional integrity.
