Spring Steel EN45

EN45 is a manganese spring steel. That is to say, it is a steel with a high carbon content, traces of manganese that affect the metal’s properties, and that it is generally used for springs (such as the suspension springs on old cars). It is suitable for oil hardening and tempering. When used in the oil hardened and tempered condition EN45 offers excellent spring characteristics. EN45 is commonly used in the automotive industries for the manufacture and repair of leaf springs.

Spring Steel EN47

EN47 is suitable for oil hardening and tempering. When used in the oil hardened and tempered condition EN47 spring steel 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 steel for parts exposed to stress, shock, and vibration.EN47 is used widely in the motor vehicle industry and in many general engineering applications. Suitable for applications that require high tensile strength and toughness. Typical applications include crankshafts, steering knuckles, gears, spindles, and pumps.
