Super Alloys – for springs in extreme environments
High performance springs are a necessity in many areas and can be the key to innovative solutions. To manage work in extreme environments with high temperatures and aggressive corrosion risk, so-called super alloys are used.
Springs which can operate under extreme conditions are needed in several industries such as oil and gas extraction, thermal processing, marine, aerospace, power generation and petrochemical processing. The exclusive materials used in these springs have a chemical composition which provides a combination of high strength, ductility and good mechanical properties, even when working at high temperatures and in highly corrosive environments.
Expertise in super alloy springs
Lesjöfors has long experience, technical calculation skills and production capacity in the area, and also stocks a standardized range of super alloys in sheet, strip and wire suitable for springs. Examples of product areas are disc springs, compression springs, torsion springs, tension springs and leaf springs.
The following alloys are kept in stock:
- Inconel X-750
- Inconel 718
- Nimonic 90
- Hastelloy C-276
- MP 35N
- AISI 316
- Alloy 3J21 (Elgiloy)
In addition to these, a number of other alloys are orderable.
New super alloy in stock
Alloy 3J21, also known under names such as Elgiloy and Phynox, is new in the assortment. It is a Cobalt-Chromium-Nickel alloy which gives a combination of high strength, ductility and good mechanical properties and is age hardenable. Alloy 3J21 also has excellent fatigue life, corrosion resistance in numerous environments and is non-magnetic.
