Why is heat treatment used in the production of Rail Clips?

As a leading manufacturer of rail fastening industry in China,GNEE RAIL is extremely capable of producing elastic rail clips for any type of toe load and axle load requirements to fix steel rails on wooden, steel or concrete sleepers. We offer various types of elastic rail clips with size steel bar diameter from 12mm to 20mm. We manufacture different types of elastic rail clips with flat toe for broad gauge line, having the toe load from 850kgf to 1100kgf, and are capable of providing any type of toe load and axle load to fix the rails on wooden, steel or concrete sleeper.

When spring steel deflection is 9.1mm, fatigue life is up to 5 million cycles without breaking.

Heat treatment is used in the production of rail clips to improve their mechanical properties, such as strength, hardness, and durability, to ensure they can withstand the extreme pressure of holding train tracks in place and resist wear and weathering over many years. This process involves controlled heating and cooling to create a more resilient clip that is less likely to fail or deform.

Key benefits of heat treatment for rail clips

• Increased strength and hardness: Heat treatment processes like quench and temper make the steel clips significantly stronger and harder, allowing them to securely hold tracks under the immense weight of trains.

• Enhanced wear resistance: By controlling the micro-structure of the steel, heat treatment can make the surface of the clips more resistant to the abrasion and wear caused by constant friction.

• Improved toughness and flexibility: Heat treatment can also increase toughness and flexibility, which helps prevent brittle fracture and allows the clip to withstand the vibrations and stress of passing trains.

• Increased service life: The combined improvements in strength, wear resistance, and toughness lead to a longer service life for the clips, reducing the need for frequent replacement.

• Stress reduction: Processes like tempering are used to reduce internal stresses that may have built up during manufacturing, which further prevents failure.

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.
