Uddeholm Sleipner

A VERY GOOD STEEL FOR ALL TYPES OF SURFACE TREATMENTS

Close-up of a metallic injection mold with several cylindrical guide pins and detailed cutouts, designed for shaping or manufacturing parts in industrial production and ideal for cold work tooling applications.

Uddeholm Sleipner is a general purpose steel for cold work tooling. It has a mixed-abrasive wear profile and a good resistance to chipping. Furthermore a high hardness (>60 HRC) can be obtained after high temperature tempering. This means that surface treatments such as nitriding or PVD can be made on a high strength substrate. Also, it means that complicated shapes with hardness levels >60 HRC can be wire EDM’d from blocks with relatively thick cross-sections with a much reduced risk of cracking.

Uddeholm Sleipner is recommended for medium run tooling applications where a resistance to mixed or abrasive wear and a good resistance to chipping are required.

Benefits

  • Very broad property profile
  • Very good steel for all types of surface treatments
  • Extremely versatile conventional tool steel for medium run cold work tooling
  • Suitable upgrade where added chipping or wear resistance is needed over traditional AISI A2 or AISI D2

In East/South East Asian countries served by ASSAB, Uddeholm Sleipner is sold as ASSAB 88.
