Uddeholm Sleipner

A VERY GOOD STEEL FOR ALL TYPES OF SURFACE TREATMENTS

Uddeholm Sleipner is a high alloyed tool steel with a very broad property profile. It is also a very good steel for all types of surface treatments. This combination means that Uddeholm Sleipner is an extremely versatile conventional tool steel for medium run cold work tooling. In East/South East Asian countries served by Assab, Uddeholm Sleipner is sold as Assab 88.
