Inconel springs refer to springs made of Inconel alloy materials. They have high strength and corrosion resistance, are suitable for extreme environments, and are commonly used in the fields of petroleum, chemical industry, mining, navigation, aerospace, etc. Inconel includes different materials, each with different characteristics. The following table lists the common Inconel material types and characteristics.
| Name | Feature |
| Inconel 600 | solid solution reinforcement |
| Inconel 601 | High temperature oxidation resistance, corrosion resistance, high mechanical strength, easy to process |
| Inconel 625 | Acid resistance, good weld ability. |
| Inconel 690 | Low cobalt content and low resistivity for nuclear applications |
| Inconel 713C | Precipitation-hardened nickel-chromium base cast alloy |
| Inconel 718 | Gamma double prime reinforced with good weld ability |
| Inconel X750 | Excellent relaxation resistance is useful for high-temperature |
| Inconel 751 | Increased aluminum content to increase fracture strength in the 1600 °F range |
| Inconel 792 | Increased aluminum content to improve high-temperature corrosion performance, especially for gas turbines |
| Inconel 939 | Gamma prime reinforced to improve weld ability |
| Commonly used are Inconel 600, Inconel 601, Inconel 617, Inconel 625, Inconel 718, Inconel x750, etc. | |
Inconel Spring Manufacturing Process
Manufacturing high-quality Inconel springs is complex, involving several critical steps. These include coiling (cold coiling for wire diameters of 20mm or less, and hot coiling for diameters above 20mm), heat treatment to relieve stress, and quenching and hardening. Each process requires precise control of temperature, duration, and cooling methods, demanding extensive professional knowledge. It's not just about having the right equipment. For instance, solution treatment involves heating and rapid cooling to evenly distribute alloying elements and improve ductility, while aging treatment holds the material at a moderate temperature to increase strength and hardness. Quenching heats the spring and rapidly cools it to harden the material while maintaining elasticity, followed by tempering to reduce brittleness. Additionally, the quality of the material is crucial. Sourcing Inconel alloy from reputable suppliers is essential to avoid counterfeit materials that could compromise the final product's quality. Ensuring dimensional accuracy, mechanical performance, and proper surface treatment further guarantees the spring's reliability and durability.
