Compression Springs
Offshore Stainless Supplies has earned a strong reputation as a premium supplier of cold drawn bars to spring manufacturers, offering a broad portfolio of strain hardened bars in both stainless steel and nickel alloys that ensure high strength and fatigue resistance. With a focus on bars starting at 8mm diameter up to 4” diameter, we supply cold drawn bars for compression springs that are designed to withstand the extreme demands of the oil and gas sector, as well as other industries like aerospace, chemical processing and power generation.
​
For manufacturers of compression springs, choosing the right material is paramount to ensure performance and durability in these harsh environments. Springs made from stainless steel and nickel alloys are often the only solution for such applications, and this is where Offshore Stainless Supplies excels.

Key products and material grades including Super Duplex and 316 stainless steel offer excellent corrosion resistance, particularly in chemical, marine and chloride-rich environments, making it ideal for offshore and subsea applications.
​
Our C276 nickel alloy is a material of choice for highly corrosive environments, particularly in sour gas and chemical processing applications. Furthermore, our Inconel 625 and 718 superalloys are essential for applications requiring high strength, corrosion resistance and the ability to maintain performance at elevated temperatures.
​
By cold drawing a pre-determined oversized bar to its finished diameter size, the bars achieve higher yield and tensile strength, essential for springs that must withstand heavy loads. The precision of the cold drawing process ensures that bars meet exacting size requirements, which is crucial for spring manufacturers to produce components with consistent performance.
​
An Offshore Stainless Supplies customer recently partnered with a leading manufacturer of subsea control valves. The customer required 316 stainless steel bars for springs to be used in a deepwater subsea valve project. By providing precision cold drawn bars with superior corrosion resistance, we ensured that the springs performed reliably, reducing the risk of valve failure in harsh subsea conditions.
​
Offshore Stainless Supplies also recently produced nickel alloy 718 cold drawn bars for a spring manufacturer for a provider of downhole tools for springs used in high-temperature, high-pressure drilling applications. We delivered cold drawn bars that met exacting standards, enhancing tool performance in extreme environments and prolonging the service life of the components.
​
Offshore Stainless Supplies has built its reputation on delivering high quality materials and providing expert advice to spring manufacturers. Our focus on quality control and materials testing ensures that every batch of stainless steel and nickel alloy bars meets industry standards, including ASTM and NACE specifications. We also have an extensive range of nickel alloys available for cold drawing, and we welcome enquiries for any non-standard products to meet any specific customer requirements.
​
We provide tailored solutions for specific customer needs, ensuring that spring manufacturers receive the exact material dimensions and mechanical properties required for their applications, producing large compression springs that ensure safety and efficiency in some of the world’s most challenging industrial environments.
