Inconel Springs

Inconel springs are useful in applications where other springs may fail. SMSC produces industry-grade Inconel springs that are ideal for extreme environments, and mission-critical applications. These industrial springs are made from Inconel X-750 alloy. We source our materials from reputed dealers, which allows us to provide springs in the unmatched quality.

Technical Information -Inconel X-750 Alloy

Inconel X-750 alloy is a nickel-chromium alloy, which exhibits excellent physical, as well as thermal properties. The springs manufactured from this alloy can withstand temperatures as high as 1300°F (704° C). The following technical data will help you understand composition, as well as properties of this alloy.
