EN 41B
EN 41B is a low-alloy steel that falls under the European standard EN 10083-3. It is also known by its alternative designations, including 41CrAlMo7 and 1.8509. The "EN" in EN 41B indicates that it conforms to European standards.
EN 41B steel is primarily used in the manufacturing of high-strength machine parts, such as gears, crankshafts, camshafts, and fasteners. It offers a combination of good toughness, high tensile strength, and wear resistance, making it suitable for applications subjected to heavy loads and high stress.
The chemical composition of EN 41B steel typically includes elements such as chromium (Cr), aluminum (Al), molybdenum (Mo), carbon (C), and manganese (Mn). The specific composition may vary depending on the manufacturer or standard specifications.
