Inconel 718 Extension Springs are precision-engineered for high-performance tension
applications, especially in aerospace, nuclear, marine, and petrochemical industries. Manufactured
by FERROBEND using Inconel® 718 alloy
(UNS N07718, 2.4668),
these extension springs offer exceptional strength, fatigue resistance, and reliable tension under
extreme conditions. The wire composition
(NiCr19Fe19Nb5Mo3),
ensures excellent corrosion resistance and creep rupture properties even at elevated temperatures.
Compliant with ASTM B637,
EN 10269,
and other international wire spring standards, these springs are available in custom hook styles
and load ratings. Designed to deliver consistent performance in demanding environments, they
maintain elasticity and mechanical integrity in oxidizing, reducing, or corrosive atmospheres.
FERROBEND extension springs are ideal for use in engines, turbines, subsea equipment, and
high-stress industrial assemblies.
