Uddeholm Sleipner

A VERY GOOD STEEL FOR ALL TYPES OF SURFACE TREATMENTS

A close-up of a precision metal injection mold, ideal for cold work tooling applications, featuring detailed engravings, cylindrical guide pins, and complex metal components arranged on a flat metallic surface.

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. Uddeholm Sleipner is a 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.
