PACIFIC ACRALLOY® has satisfied the high strength precision shafting requirements of the Pacific Northwest for decades. Acralloy® is drawn or turned then heat treated by quenching and tempering for high strength. It is then specially straightened, stress relieved, and ground and polished to 16 maximum rms. Acralloy® has good toughness as well as high strength and is the choice for many heavy duty shafting applications. It can be welded if properly preheated. Acralloy® can also be surface hardened by induction heat treating and by nitriding.
