A time-honored
medical material

 

不锈钢是最基本的医用材料。它也是韦恩堡金属第一个拉制成丝的材料。

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.

尽管在很多要求严苛的应用中不锈钢已被钴镍合金、镍钛合金所替代,但由于其多功能性和相对较低的成本,仍是医疗行业最常用的材料。韦恩堡金属按惯例使用以下级别的医用钢:

  • 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”表示具有增强型的显微纯洁度和同质性的真空重熔材料。)
