Custom 455® Stainless Steel

In the annealed condition 455/Custom 455® is relatively soft, however with a single heat treatment it is capable of very high strength, just below that achieved by 465/Custom 465®. Cold working 455/Custom 455® before aging will enhance the strength versus aging from the annealed condition. 455/Custom 455® also has excellent corrosion resistance, similar to 465/Custom 465®. 455/Custom 455® is a Carpenter Technology registered trademark.

Common Applications

455/Custom 455® is one of the most widely used stainless steel grades for surgical instruments because of its high tensile strength and resistance to corrosion in fresh water. However, in contrast to other grades, 455/Custom 455® is not an implantable metal. Instead, it is primarily used for various surgical instruments including but not limited to surgical scissors, ear pins, rollers and guides.
