General
Uddeholm Sverker 21 is a high-carbon, high-chromium tool steel alloyed with molybdenum and vanadium characterized by:

• High wear resistance

• High compressive strength

• Good through-hardening properties

• High stability in hardening

• Good resistance to tempering-back

Applications
Uddeholm Sverker 21 is recommended for tools requiring very high wear resistance, combined with moderate toughness (shock-resistance). In addition to the applications listed in the product information brochure for Uddeholm Sverker 3, it is used when cutting thicker, harder materials; when forming with tools subjected to bending stresses and where high impact loads are involved.
Uddeholm Sverker 21 can be supplied in various finishes, including the hot-rolled, premachined and fine machined condition. It is also available in the form of hollow bar and rings.
