CUSTOM 455 PER STRYKER HMS 4553
Custom 455, defined in Stryker HMS 4553, is a corrosion-resistant stainless steel that derives its strength from precipitation hardening. It is a specially adapted material for medical devices that demand the highest performance, and the Stryker HMS 4553 standard is a detailed set of specifications for the use of Custom 455 stainless steel in critical medical and surgical procedures where performance is paramount.
This is a martensitic precipitation-hardened stainless steel with a composition that includes approximately 12% chromium, around 8.5% nickel, and additions of titanium, niobium, and copper. The unique composition allows the steel to attain extremely high levels of strength after precise heat treatment, in addition to its excellent resistance to corrosion. The unique combination of its superior mechanical properties and its excellent resistance to corrosion make it a first choice for difficult medical and biomedical applications.
Product Forms & Size Range
Custom 455 per Stryker HMS 4553 is commonly used in medical and orthopedic device manufacturing where high strength and corrosion resistance are required.
Typical applications include:
- Orthopedic surgical instruments
- Medical device components
- Implantable or non-implantable surgical hardware
- Precision medical mechanical component
