Characteristics
- 1.4310 is an austenitic chromium-nickel steel, which is widely used in medical technology.
- Special production process results in a microstructure with a high level of bending ductility.
- The α'-martensitic formation is enhanced during cold forming
- Leads to high tensile strength even atfter relatively low reduction rates.
- Bright and shiny wire surface improves productivity and reduces scrap rates.
Applications
- Surgical needles
- Surgical instruments
- Dental instruments
