What material of rail clip is the most durable?

The most durable rail clips are made from spring steel alloys like 60Si2CrA or 60Si2MnA, which are specially formulated for high strength, fatigue resistance, and durability under heavy loads and harsh conditions. While standard steel is strong, these specialized spring steel alloys offer enhanced performance and longevity for critical applications.

Top materials for durability

• 60Si2CrA: An alloy spring steel known for its superior fatigue strength and wear resistance, making it ideal for high-speed and heavy-duty railways.

• 60Si2MnA: A high-strength carbon spring steel with excellent elasticity and fatigue resistance, used in many heavy-duty and high-speed applications.

• 38Si7: An alloy steel conforming to European standards, offering good elasticity, corrosion resistance, and durability.

• Forged Spring Steel: A general category that includes specific grades like 38Si7 and 60Si2MnA. Forging improves the mechanical properties of the steel, enhancing its strength and durability.

Other durable materials

• Carbon Steel: While not as specialized as the spring steel alloys, carbon steel is a cost-effective option that still offers good strength and durability for applications without extreme corrosive elements. Protective coatings can be added to improve its resistance to corrosion.

• Cast Steel: This is a general term, but specific types like high-carbon cast steel or cast alloy steel offer high strength and are used for large, heavy-duty components in railway systems. However, they may not always have the same elastic properties as spring steels.

Key considerations

• Application: The choice of material depends on the specific application. Heavy-duty or high-speed lines require the more durable alloy spring steels, while standard applications might use less expensive carbon steel.

• Environment: For corrosive environments, materials with better corrosion resistance like 38Si7 or those with protective coatings are necessary to prevent degradation and ensure long-term durability.
•  

• Selecting of Raw Material: We choose premium strong strength grade steel as raw material for producing rail clip, the steel is reliable and from certified long term producer.

• Shearing: The spring steel need to be sheered to specified length.

• Heating: The sheared rods are heated to the 950 ℃ to 1000 ℃, but the workers must pay attention to check the decarburization.

• Forming: The heated bar is transferred to power press for forging, and then be transported to the quenching tank for quenching and tempering.

• Inspection: the clips are checked for the dimensional accuracy and quench hardness by the inspection facility.

• Surface Treatment: The surface can be oiled or other color according to the requirement of customers.

• Packing: Plastic bags and wooden pallets or other packing way according to clients' requirement.
