Selecting the right surface treatment and substrate tool steel combination is critical for achieving optimum tool life. PVD coatings provide excellent abrasion and galling resistance while maintaining the integrity of many substrate tool steels. These coatings work best when applied to high speed tool steels such as M-2, PM-M4, and T-15.

Tool steels are typically heat treated to increase their hardness and used for metal stamping, forming, shearing, cutting, and plastic forming. The carbon percentage in tool steels is typically in the range of 0.7 to 1.5 wt% carbon. However, some tool steels can contain up to 2.1% carbon, while others contain less than 0.25 % carbon.
