Material Notes:
CRUSADER (M3-2) is a high speed steel with an outstanding balance of red hardness, edge toughness and wear resistance. The additional carbon and vanadium provide good resistance to abrasion and edge breakdown, which makes Crusader a good choice for tool material for form tools and roll turning. Increased tool life will also be experienced in the machining of heat-treated sections, castings and similar hard materials. Typical applications for Crusader high speed steel include form tools, spade drills, milling cutters and broaches.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
