High-strength fishplates are used to connect two railroad rails, ensuring sufficient strength, stability, and durability at the rail joints. Compared to ordinary fishplates, these products are made of alloy steel or medium-carbon steel and undergo heat treatment, resulting in higher tensile strength, bending strength, and excellent fatigue resistance.
They are suitable for applications involving high loads and frequent vibrations, such as heavy-duty transportation in mines, railway main lines, port tracks, and crane rail systems.
The high-strength fishplates made by AGICO follow the requirements of ISO 9001:2015. They show enhanced strength, toughness, durability, wear stiffness, and elasticity. Which exhibits enough resistance to tear and wear and can cope with heavy loads and extreme weather conditions. Besides, the high-strength fishplate is a perfect match for the railroad track due to its high precision and tailor-made solution.
Core advantages of High-strength fishplate from AGICO
Higher Tensile Strength
Materials commonly used include 45# steel, 40Cr, 42CrMo, and Q450–Q690, with tensile strength reaching 600–900 MPa.
Superior Fatigue Resistance
Heat treatment processes (quenching and tempering) ensure that the rail clips do not crack under long-term load.
Excellent Impact Resistance
Maintains stable performance under low temperature and heavy load conditions, suitable for open-pit mines and cold regions.
Precise Matching of Different Rail Profiles
Customizable to international standard rail profiles: UIC54, UIC60, 60kg, 75kg, 115RE, 132RE, 136RE, QU80–QU120, etc.
Easy Installation and Maintenance
Used with high-strength bolts and spring clips for enhanced resistance to loosening.
Materials & Heat Treatment
The high-strength fishplate goes through quenching and tempering, or through-hardening and tempering, to improve yield strength, hardness, and fatigue resistance. High-strength fishplates are typically made from the following materials:
| Material | Description | Application |
|---|---|---|
| 45# medium carbon steel (quenched & tempered) | Stable performance, high cost-effectiveness | 43kg–60kg industrial rails, light railways |
| 40Cr Alloy Steel | High yield strength, strong impact resistance | Heavy-duty mining transportation |
| 42CrMo Alloy Steel | High yield strength, strong impact resistance | Heavy-duty mining transportation |
| Q450–Q690 High-Strength Steel | High strength, fatigue resistance | Heavy-duty railways, long-life applications |
