General
Uddeholm Rigor is an air- or oil hardening chromium-molybdenum-vanadium alloyed tool steel characterized by:

• Good machinability

• High stability after hardening

• High compressive strength

• Good hardenability

• Good wear resistance

Applications
Uddeholm Rigor takes a place in the Uddeholm tool steel range between Uddeholm Arne and Uddeholm Sverker 21, offering an excellent combination of good wear resistance and toughness. It may be regarded, therefore, as a "universal" cold work steel.
For cutting operations the good toughness of Uddeholm Rigor gives excellent resistance to chipping of the cutting edge. In many cases tools made from this steel have given better tooling economy than high-carbon, high-chromium steel of the BD3/W.-Nr. 2080 type. Uddeholm Rigor has much better machining and grinding properties.
