Alloy Steel F11 contains 1–1.5% chromium, 0.4–0.65% molybdenum, and a balanced amount of carbon steel. It provides tensile strength up to 585 MPa and yield strength around 275 MPa, along with good hardness and toughness. This alloy resists thermal fatigue, oxidation, and scaling. It maintains stability under continuous exposure to high temperatures and is commonly used in systems that require strength under pressure and heat.
