Custom Spring Manufacturing Materials

Many types of materials are used in custom spring manufacturing, depending on the application and the needs of the customer. Because our customers work in the energy, oil and gas industries, we understand how critical it is that our products are engineered to be as durable and reliable as possible.

For these reasons, we typically use the following metal alloy materials in the custom spring manufacturing process.

Inconel X-750

Inconel X-750 is a nickel chromium alloy originally developed for use in the high-stress environment of nuclear energy generation. This material is considered the gold-standard in spring manufacturing, as it provides the maximum corrosion and temperature resistance (up to 1300º F). In fact, the National Association of Corrosion Engineers (NACE) has approved Inconel X750 for downhole gas exposure.

Hastelloy C-276

Hastelloy C-276 offers improved performance over stainless steel products but is more cost-effective than other materials. This corrosion-resistant material is a nickel molybdenum chromium alloy with tungsten. Hastelloy C-276 can withstand up to 750º F and is resistant to crevice corrosion, pitting and oxidizing agents. It is often used in sour gas wells and other especially severe conditions.


Considered in the industrial sector to be a “super alloy,” Elgiloy contains a mixture of iron, nickel, chromium, manganese, cobalt and molybdenum. This non-magnetic material resists corrosion – particularly chlorides – and is appropriate for use at very high temperatures (up to 850º F.) Elgiloy is the ideal material for providing maximum strength in a small space.

Other Spring Manufacturing Materials

In addition to the three metal alloy materials listed above, we also use a variety of other materials, depending on the desired outcome and the manufacturing processes used. These include:

  • Chrome silicon – this material, with high tensile strength and resilience under moderately high temperatures, tolerates high stress and impact well.
  • Music wire – this material, a high-carbon steel alloy with a high elastic limit and tensile strength, tolerates high stress and corrosive environments.
  • MP35N – this material, a corrosion-resistant cobalt nickel chromium alloy, offers good fatigue life and high strength.
  • 17-7 Stainless Steel – this material, containing chromium, nickel and aluminum, can withstand temperatures up to 650º F with high strength and corrosion resistance.
  • 300 Series Stainless Steel – this material, an alloy steel containing chromium and nickel for added corrosion resistance, is strong and non-magnetic.

We can recommend the most appropriate materials for your springs, depending on whether you plan to use them under extremes of pressure or temperature, or in a particularly caustic environment.
