AISI 904L Springs

AISI 904L Springs

AISI 904L Springs are precision mechanical fasteners designed to store and release energy through simple pushing and pulling forces. These springs are available in a wide range of types including helical compression springs, conical compression springs, helical extension springs, torsion springs, Belleville springs, and flat springs.

Adfast Components manufactures and supplies AISI 904L springs in both metric and imperial sizes. The springs are produced from ASTM A182 F904L forged material and ASTM A276/A276M as well as A479/A479M bar stock specifications. Each stainless steel 904L spring is manufactured in accordance with ASME, DIN, ISO, UNI, PN, BS, and BIS dimensional standards.

For quality assurance and traceability, every spring is duly marked. Adfast Components ensures global delivery through reliable sea and air freight options.
