Stainless Steel Spring & Hardwire

Stainless Steel Spring & Hardwire

Stainless Steel wire is often used as stainless steel spring material. Most prevalent stainless steel spring grades are stainless steel grade 302 and to a lesser extent stainless steel grade 316 (corrosion resistance).

The stainless steel spring and hardwires are exhibiting the high tensile level often referred to as “spring temper” which can exceed 2000N/mm². Stainless steel wires are used in a variety of springs: compression springs, extension springs, torsion springs, aerosol springs and other applications such as stainless steel music wire (piano wire, guitar wire)

SADEVINOX has an extensive stainless steel wires stock.
