A time-honored
medical material

 

Stainless steel is the most basic medical material. It’s also the first material we ever drew into wire at Fort Wayne Metals.

We begin the stainless steel drawing process with our carbide dies for diameters greater than 0.100” (2.54 mm). From there, we transition to our polycrystalline dies for diameters between 0.100” (2.54 mm) and 0.040” (1.016 mm). These two die types provide a relatively rough surface which can be enhanced with additional finish treatments. Our single crystal natural diamond dies will take your stainless steel wire from 0.040” (1.016 mm) all the way down to our fine wire sizes. As stainless steel wire gets drawn to the finer sizes, it develops a more polished appearance.

While Stainless steel has been replaced by materials such as Cobalt-Chrome, Titanium or Nitinol in many demanding applications, it is still the most commonly used material for medicals due to its versatility and relatively low cost. Fort Wayne Metals routinely works with the following grades of surgical steel:

  • 302 (ASTM A313/A313M · ASTM A276 · ASTM F899)
  • 304V (ASTM F899, ASTM A276, ASTM A313/A313M)
  • 304LV
  • 316LVM (ASTM A276 · ASTM A580 · ASTM F138 · ISO 5832-1)
  • Custom 455® (ASTM A564/A564M· ASTM F899)

(“V” denotes vacuum remelted material with improved microcleanliness and homogeneity.)
