High Strength Steels
Mirraloy® FM Pre-Keyed
Free Machining, Turned Ground & Polished, Full Length Keyed Shaft
Mirraloy FM Pre-Keyed is designed to provide a high degree of accuracy while also exhibiting high strength, ease of machining, and long-term wear life. Most other keyed shafts are typically “Cold Roll” which generally means you get mild steel. Typical hardness is Rockwell “C” 26. This shafting material is based on a modified 1144 steel.
Provides superior strength and toughness in service due to its micro alloyed chemistry. The following tests: roto bar, mechanical, warpage, and machinability are performed at the manufacturing level, prior to keying the shaft, to ensure proper product performance in the field.

Exhibits nearly 50% more tensile strength than that of a C1018 and up to 25% more than C1045.
