At Central Wire, our alloy capabilities are a main reason why so many companies rely on us to fulfill their project needs. Finding manufacturers with the knowledge, manufacturing capabilities, and depth of raw materials that we have can be a very difficult task, which is why we remain a trusted supplier for global leaders across various industries.
A Trusted Spring Wire Supplier
Our Spring Wire product line leans on the reliability of our manufacturing and raw materials, which are built to handle repeated use in harsh conditions. Our wire provides excellent coiling ability at high speeds, and rarely requires any additional lubricant.
Quality control and premium raw materials are the main reasons why we are a trusted source for Spring Wire, catering to various different industries. We manufacture a full line of economical corrosion-resistant Spring Wire in stainless, nickel and other alloys.
All of our Spring products can be certified to ASTM A313 or other industry standards, as well as manufactured to your custom specifications. The quality and coiling ability of our Spring Wire preserves equipment life, minimizes downtime, and maximizes your throughput and profits.
17-7PH®: A Central Wire Specialty
One of the strongest and most versatile alloys we provide, 17-7PH® is a standout in this product line and beyond.
Central Wire is the leading producer of Aerospace and Commercial quality 17-7PH® Spring Wire in both the United States and the United Kingdom. We lean on our decades of metallurgical experience with processing this alloy to meet the specifications of the spring applications that we serve.
Our research and process development, and tight control on several wire-drawing parameters help optimize the microstructural characteristics of our 17-7PH® Spring Wire to be fully compliant with AMS 5678G standards.
What Makes 17-7PH® Stand Out
17-7PH® is a chromium-nickel-aluminum precipitation hardening Stainless Steel which offers similar corrosion resistance to 302, but can achieve higher strength after precipitation hardening due to its aluminum additions.
It is an ideal alloy for applications that require good formability, high strength and hardness, and minimum distortion upon heat treatment. 17-7PH® also provides excellent properties for flat springs at temperatures as high as 315°C (600°F).
The alloy begins as an austenitic structure in the solution treated stage. Through strain and coldwork during the wire-drawing process, the material transforms to a martensitic structure that is finally further strengthened through the aging process which forms submicroscopic nickel-aluminum based precipitates increasing the material’s hardness and strength.
Its chemical composition is as follows:
UNS S17700 – Al: 0.75-1.50, Cr: 16.0-18.0, Ni: 6.5-7.75
Spring Wire Applications in Demanding Industries
The quality and expertise behind our Spring Wire manufacturing helps us meet the demanding conditions of the modern industries that we serve. Our Spring Wire can be found in mission-critical Aerospace applications, as well as various commercial industries, including:
- Agriculture: Strength and consistency play a pivotal role in livestock fencing, gates, and inside harvesting equipment.
- Architecture: Stainless Spring Wire adds aesthetic and functional value to architectural projects.
- Marine: Marine applications require the corrosion resistance of 300 series stainless steel to withstand salt and moisture exposure.
- Mining: Spring Wire used in modern mining must be able to withstand crushing forces, intense vibration and heavy weight.
- Oil and Gas: Downhole applications require the corrosion resistance and high strength of our stainless Spring Wire.
