High-Tensile Chrome Silicon Springs, ASTM-A401 Wire
Coiling Technologies manufactures custom high-tensile chrome silicon springs for automotive, military, construction, and other industries. Chromium silicon alloy wire is an ideal material for fabricating springs. Its high tensile strength and temperature resilience make it popular, especially for heavy shock loads and moderately high temperatures.
Properties of High-Tensile Chrome Silicon Springs
Chrome silicon springs have a high tensile strength and resilience. They are resistant to set when exposed to moderately elevated temperatures (maximum 246 degrees Celcius or 475 degrees Fahrenheit). The material meets ASTM-A401 wire specifications.
Coiling Technologies manufactures chrome silicon springs with a minimum size of 0.016 inches or 0.406 mm.

Manufacturing Process
High-tensile chrome silicon springs are manufactured by one of two methods:
- Annealed and cold drawn: The steel is heated to an appropriate temperature, maintained for a particular time, and slowly cooled. The process improves the material's ductility and machinability.
- Oil-tempered: The wire is heated to an extreme temperature and then cooled with oil. The process strengthens it without making it brittle.
Either process is acceptable under ASTM-A401 wire standards.
Advantages of Chrome Silicon Springs
The manufacturing process of chrome silicon makes it stronger. It maintains its consistent performance for a long time, even under repeated spring loads.
Benefits of Purchasing From CTI
Purchasing from Coiling Technologies gives you the advantage of our ISO-certified process, shorter turnaround times, and high technology levels.
Applications for Chrome Silicon Springs
Chrome silicon springs are best suited for applications that must withstand shock loads, lightly stressful applications, and moderately high-temperature environments. They can handle more stress and heat than other spring wires, like music wires.
Common uses for chrome silicon wire include gun recoil springs, fuel equipment, and engine valve springs for high-performance vehicles.
