Difference Between Stainless Steel Wire and Music Wire

What is Music Wire ?

Music Wire is a common name for high carbon spring wire.  This product is used for countless spring applications.  It received its name because it was originally used for Piano wire.  This high tensile wire can withstand temps up to 250 degrees Fahrenheit, has high fatigue life, as well as, take severe bends without cracking. However, it is not recommended for springs that will be exposed to humidity or moist environments, as it is prone to rusting in these conditions.

What is Stainless Steel Wire ?

Stainless Steel Wire is quite a popular material for metal coil springs. There are three main types of stainless steel wire: Stainless Steel 302 (ASTM A-313), Stainless Steel 316 (ASTM A-316), or Stainless Steel 17-7 (ASTM A-313).
The most popular and most recommended type of Stainless Steel is Stainless Steel 302 and it can resist temperatures as high as 550º F (288º C).

What is differece between Music Wire and Stainless Steel Wire?

Music Wire is actually stronger than Stainless Steel Wire. However, unlike music wire, stainless steel Wire can withstand much higher temperatures and will not rust in humid or corrosive conditions. This makes stainless steel springs ideal for medical applications and high temperature conditions.
