Inconel 625 Spring Washers
Inconel 625 Spring Washers, also known as Alloy 625 Split Type Lock Washers, are precision-engineered
split-type components manufactured from UNS N06625 / 2.4856 / NiCr22Mo9Nb alloy. Designed for critical
bolted assemblies, these washers provide excellent tension retention and vibration resistance across
high-temperature and corrosive environments. Manufactured in accordance with ASTM B637, ASTM A1014, and EN 10095, FERROBEND produces a wide stock inventory of spring washers in both Metric (M3 to M100) and Inch
sizes (#6 to 4") for immediate dispatch. Dimensional standards include DIN 127, ASME B18.21.1, JIS B 1251,
BS 4464, IS 3063, and UNI 1751. These Inconel 625 split lock washers are ideal for use in marine,
petrochemical, and aerospace applications requiring long-term performance and high fatigue strength.
Manufacturing is based in India, with global exports under the FERROBEND brand name, offering both
standard and custom washer solutions.
