• CHARACTERISTICS - O1 is an oil-hardening, non-deforming tool steel which can be hardened at relatively low temperatures. Tools and dies made from O-1 will have good wearing qualities since the tungsten and higher chromium content gives improved wear resistance over the straight manganese grades.
• WORKABILITY - - Machinability is high. Grindability is high.
• APPLICATIONS - Blanking Dies, Bushings, Forming Dies, Master Tools, Forming Rolls, Guages, Trim Dies
