What are the advantages of using 38Si7 to manufacture Rail Elastic Clips?

Rail clip, also called elastic rail clip, it is used to fasten the rail tracks with railroad spike, rail pad, track bolt, rail joint bar together. It is also usually used as a part of rail fastening system. There are huge demand of rail clips on the railway line, about 7000pcs per kilometer, which is directly related to rail safety.

Using 38Si7 spring steel for rail elastic clips offers advantages such as high fatigue resistance, good mechanical properties, and improved durability, thanks to its composition and ability to be optimized through heat treatment. This medium-carbon steel is known for its reduced decarburization sensitivity and strong plastic properties after heat treatment, which lead to enhanced performance and longer service life for the clips in demanding railway applications.

Advantages of using 38Si7

• High fatigue resistance: 38Si7 is a medium-carbon spring steel known for its improved fatigue resistance, which is crucial for components like rail clips subjected to constant stress.

• Excellent mechanical properties: After proper heat treatment, 38Si7 can achieve high tensile strength, a good reduction in area, and increased elongation, making the clips strong and resilient.

• Enhanced durability: The combination of high strength and flexibility provides long-lasting performance in railway applications, which require components to withstand harsh conditions.

• Reduced decarburization sensitivity: Compared to high-carbon spring steels, 38Si7 has a lower sensitivity to decarburization, which helps maintain the strength and plasticity of the finished product.

• Optimized for cost and performance: The material can be manufactured with optimized heat treatment processes to achieve high-performance, low-cost clips suitable for large-scale railway projects.

Types of rail clip

• According to specific situation and habit, various countries adopts different standard of rail clips to apply for development of railway. Typically, the Pandrol series of rail clip is the most famous brand among rail clip types. PR- clip, E-clip are widely separated to America, Canada, India and other countries.

• In German, HM-type rail fastening system is very popular, it adopts SKL-clip. Based on the good effect, it is applied to a lot of countries and regions.

• Dutch DE type railway fastening system and FIST rail fastening system all adopt rail clips, they all have good application.

• Japan and France adopts clips as rail fastening system, Nabla rail fastening system and 102 type fastening system are hot on the market.

As an OEM & OBM manufacturer, GNEE RAIL is capable of not only producing a wide range of internationally common types of rail clips, such as W Tension Clamp, e-Clip, Fast-Clip, SKL Tension Clamp, Nabla Blade, etc., but also customizing products tailored to our customers' specific requirements.
