Regol HR Alloy

Color Code Red | Heat Treated • Stressed Relieved • High Tensile

REGOL HR is an electric-furnace, fine grained alloy steel delivered in the heat-treated hardness of 28-32 Rockwell C. REGOL HR can be used without further heat treating for many applications. The blend of nickel, chrome, molybdenum, and manganese results in superior physical properties, yet it is still classified as a free machining steel with excellent toughness and good ductility. Machine straightening and stress relieving complete the rigid manufacturing cycle of all REGOL HR steels.
