High Strength Materials

SHEFFIELD™ #20 FM TGP – Free Machining TGP Shaft

Sheffield #20 FM is an alloyed, hybrid, carbon steel that offers both a high degree of machinability, like a carbon steel, but has the strength consistent with an alloy steel.

Sheffield #20 FM does not exhibit hard and/or soft spots similar to what is seen in most carbon steels. It is designed for ease of machining with high speed automatic equipment, such as screw machinery.

Sheffield #20 FM should be considered as an upgrade when drawings or prints specify; 1018, 1045, 12L14, 1141, and 1144.
