Alloy Steel Grade 11 Foils are mainly made up of chromium (1–1.5%), molybdenum (0.45–0.65%), and a foundation of carbon steel. This alloy also contains trace amounts of manganese, phosphorus, sulfur, and silicon to boost performance. These foils are known for their impressive high-temperature strength, oxidation resistance, and enhanced corrosion resistance compared to regular carbon steel. Mechanically, Grade 11 boasts a tensile strength of around 415 MPa and good creep resistance. Its excellent weldability and formability make it perfect for high-pressure and thermal applications where maintaining structural integrity is crucial under tough conditions.
