Cold Drawn Bars for High-Performance Springs
When it comes to manufacturing high-performance compression springs, the choice of material is critical. Springs are often required to operate reliably under extreme loads, corrosive environments and elevated temperatures, particularly in sectors such as oil and gas, aerospace, chemical processing and power generation.
​
At Offshore Stainless Supplies, we have built a reputation as a premium supplier of cold drawn bars for spring manufacturers, offering a broad portfolio of strain-hardened Stainless Steel and Nickel Alloy bars that deliver high strength, fatigue resistance, and precise dimensional accuracy.
Why Material Choice Matters for Springs
Compression springs must maintain their mechanical properties under repeated stress cycles, and the wrong material can lead to fatigue failure, corrosion, or premature wear. Stainless Steels such as 316 and Super Duplex provide excellent corrosion resistance in marine, offshore and chloride-rich environments, making them ideal for subsea and offshore applications.
For highly aggressive conditions, our C276 Nickel Alloy is particularly suited for sour gas, chemical processing and other corrosive environments, while Inconel 625 and 718 superalloys are essential for applications demanding high strength, corrosion resistance and elevated temperature performance.
The cold drawing process plays a key role in achieving the properties required for high-performance springs. By drawing a pre-determined oversized bar down to its finished diameter, the material develops enhanced yield and tensile strength, ensuring springs can withstand heavy loads. Precision cold drawing also ensures tight dimensional tolerances, giving spring manufacturers the consistency needed to produce components that perform reliably under repeated stress cycles.
Real-World Applications
Offshore Stainless Supplies has partnered with leading manufacturers to supply cold drawn bars for critical spring applications. In one project, we provided 316 Stainless Steel bars for compression springs used in deepwater subsea control valves. By supplying precision cold drawn bars with superior corrosion resistance, we helped ensure the springs performed reliably, reducing the risk of valve failure in harsh subsea conditions.
In another example, we produced Inconel 718 cold drawn bars for springs used in downhole drilling tools. These springs required high-temperature and high-pressure performance, and our bars met the stringent standards necessary to enhance tool reliability and extend component service life in extreme environments.
Strength, Corrosion Resistance and Precision
At Offshore Stainless Supplies, we combine technical expertise, precision manufacturing and rigorous quality assurance to provide cold drawn bars that support high-performance springs in the most demanding industries. Our portfolio spans bars from 8mm diameter up to 4”, covering Stainless Steels, Super Duplex and a wide range of Nickel Alloys, all engineered to deliver strength, corrosion resistance and fatigue reliability.
