EN-47
EN47 is a chromium-vanadium spring steel, often referred to as oil-hardening steel. It's known for its high tensile strength, toughness, and resistance to wear and abrasion, especially when oil-hardened and tempered. EN47 is commonly used in the automotive industry and other general engineering applications where these properties are needed, such as in crankshafts, steering knuckles, gears, and various spring components.
