Huge width wire springs, otherwise called heavy duty springs, are utilized for applications that require more power than normal springs. These springs are incredibly durable and intended to ingest shock and vibration. This kind of spring is great for hardware that requires a heavy burden force.
Uses of heavy duty springs:
Raw Materials:
EN 45 is a European standard for a type of high carbon steel wire that is commonly used in the manufacturing of heavy-duty springs. The material is also known as 55Si7 or AISI 9255 in other countries.
EN 45 is a European standard for a type of high carbon steel wire that is commonly used in the manufacturing of heavy-duty springs. The material is also known as 55Si7 or AISI 9255 in other countries.
EN 45 steel wire has a high tensile strength, good toughness, and excellent fatigue resistance, making it an ideal choice for springs and other applications where high strength and durability are required. It is typically used in the production of heavy-duty springs for automotive and industrial applications, such as suspension springs, valve springs, and clutch springs.
EN 47 is another European standard for a type of high carbon steel wire that is commonly used in the manufacturing of heavy-duty springs. It is also known as 50CrV4 or AISI 6150 in other countries.
EN 47 steel wire has a high tensile strength, good toughness, and excellent fatigue resistance, similar to EN 45. However, it also has the added benefit of high resistance to wear and abrasion, making it a popular choice for springs and other applications that require high strength and durability under harsh conditions.
51CrV4 is a high-grade alloy steel that is commonly used in the manufacturing of heavy-duty springs. It is a low-alloy steel with a high carbon content, which provides it with excellent hardness, strength, and toughness.
51CrV4 steel is often used in the production of springs that require high levels of fatigue resistance and durability, such as those used in automotive suspension systems, heavy machinery, and agricultural equipment. It is also commonly used in the production of flat springs and other types of high-stress components.
The material has good hardenability, which means it can be heat-treated to achieve desired mechanical properties. It also has good wear resistance, which allows it to maintain its performance under harsh conditions.
