Exotic Alloys for Springs

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.

Elgiloy

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.
