PremoMet®

UNS #K63835

PremoMet® is a premium-melted, cobalt-free, high strength, high toughness quenched, and tempered alloy. It attains a typical 290 ksi (1999 MPa) UTS combined with a typical range of 60-65 ksi sqrt(in) (66-71 MPa sqrt(m)) fracture toughness. It also exhibits excellent fatigue life of 180 ksi (1241 MPa) stress at 1x10^7 cycles Run-Out in Axial (R=0.1, Kt=1, 25 Hz) Fatigue. PremoMet® is not a stainless alloy and may require plating or coating with a rust preventative or oil to prevent corrosion.
