Bohler-Uddeholm ROLTEC SF Cold Work Tool Steel (discontinued **)
Categories:	Metal; Ferrous Metal; Alloy Steel; Chrome-moly Steel; Tool Steel; Cold Work Steel
Material Notes:	Chromium-molybdenum-vanadium alloyed steel The ROLTEC SF steel grade is a high alloyed spray formed cold work tool steel offering a combination of high wear resistance, good resistance to cracking, and high compressive strength. The properties and manufacturing process make ROLTEC SF suitable for the production of forming rolls and slitter/shearing knives. ROLTEC SF is characterized by: High wear resistance High compressive strength High toughness Good dimensional stability at heat treatment and in service Very good through hardening properties Very good resistance to tempering back Good WEDM properties Good surface treatment properties
