Description
EN47 Spring Steel
EN47 Spring Steel is available in Round Bar form. EN47 is a chromium vanadium spring steels bar grade available in round bars.
EN47 Round Bar Spring Steels Supplied in the as rolled condition. EN47 is suitable for oil hardening and tempering. When used in the oil hardened and tempered condition EN47 Spring Steels combines spring characteristics with good wear and abrasion resistance. When hardened EN47 offers excellent toughness and shock resistance which make it a suitable alloy spring steels for parts exposed to stress, shock and vibration.
EN47 is also known as Oil Hardening Steel.

Applications of EN47 :
EN47 is used widely in the motor vehicle industry and many general engineering applications. Suitable for applications that require high tensile strength and toughness. Typical applications include crankshafts, steering knuckles, gears, spindles and pumps.
EN47 mainly used for tractors, heavy vehicles, stress and the diameter of the larger plate spring, industrial production load and helical spring. It is also used widely in many general engineering applications. When EN47 bar hardened it gives excellent shock resistance and toughness which make it a perfect alloy spring for parts exposed to shock, stress and vibration.
