What is the yield strength of Rail Clips?

Rail elastic clip is one of the popular fastening parts to keep rail track fixed on rail sleepers(wooden sleeper and concrete sleeper). Rail clamps are also used in some rail fastening systems.

The yield strength of rail clips varies significantly based on the specific material and design, but it is typically in the high-strength range, such as 81,000 to 92,000 psi for a Grade 5 bolt equivalent, or a minimum of 830 N/mm² (120,000 psi) for specialized clips like the Beket KPO 6. Materials can range from high-carbon steel to specialized alloys, with properties like the minimum yield strength determined by standards like ASTM or ISO.

Typical yield strengths

• High-strength steel: 81,000–92,000 psi (for equivalent grades like Grade 5 bolts).

• Specialized rail clips: Some specific types can achieve higher values, with the Beket KPO 6 clip's minimum yield strength being 830 N/mm² (120,000 psi).

Factors influencing yield strength

• Material composition: The specific alloy and carbon content of the steel used will determine the yield strength.

• Manufacturing and heat treatment: The manufacturing process and any subsequent heat treatments are crucial for achieving desired mechanical properties.

• Product standards: Rail clip manufacturers must meet certain standards (like ASTM or ISO) that define the minimum yield strength for a specific grade or class of fastener.

• Specific design: The design of the clip, including its shape and intended application (e.g., heavy freight lines vs. high-speed rail), can affect the required material strength.

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.
