309 stainless steel spring wire

Stainless steel spring wire is a specialized material designed for creating springs and other components that demand excellent corrosion resistance and high tensile strength, maintaining these properties even in challenging, corrosive environments. This wire achieves a high tensile level, often referred to as "spring temper," with strengths exceeding 2000 N/mm². This makes stainless steel spring wire ideal for various applications, including compression springs, extension springs, torsion springs, and specialty uses like music wires for pianos and guitars.
