**Alloy Steel 4140 Foil** is crafted from a chromium-molybdenum low-alloy steel, containing about 0.40% carbon, 0.90% chromium, and 0.20% molybdenum. This unique blend strikes a perfect balance between strength, hardness, and toughness, especially after undergoing heat treatment. The foil is thin yet maintains impressive mechanical properties, boasting tensile strength between 655–1080 MPa and excellent fatigue resistance. Additionally, 4140 foil provides good wear resistance, moderate corrosion resistance, and can be easily machined or formed as needed. It is typically available in annealed, normalized, or quenched and tempered conditions, depending on the intended application.
