Our stainless steels are non magnetic and bio-compatible and therefore have many applications within medical technology. In addition to this they have good corrosion resistance properties.
DN Meditech utilizes 1.4031 and 1.4310 for the production of wire for medical applications.
- Diameter range currently > 0.20 mm - < 5.0 mm
- Diameter tolerances as tight as ± 0.005mm are possible
- Types of packaging (eg. on spool type SK 250)
- 3.1 Mill test certificate
1.4031
Characteristics and scope of application
- 1.4031 | AISI 420 has superior properties for hardenable surgical needle production processes.
- Modified production process ensures a microstructure with minimal core carbide segregation.
- Drillability and ductility are optimally designed to meet the customer's production requirements.
- Good corrosion resistance in moderate aggressive chlorine free solvents and organic acids.
- Brilliant wire surfaces enhance productivity and reduce scrap rates.

1.4310
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.
