ABSTRACT:
Alloy for carburized bearing members intended to be used at operating temperatures up to 1000.degree.F, characterized in having the ability to achieve and retain high surface hardness after carburization coupled with good hot-workability which enables billets formed from the alloy to be pierced in a seamless tube-forming operation. Also described is the method for heat treating such an alloy to achieve the desired surface hardness, on the order of Rockwell C58 and higher. The alloy contains, as essential constituents, 0.1 to 0.3% carbon, 0.2 to 1% manganese, 0.2 to 0.6% silicon, from an effective amount up to 1.2% chromium, 2.5 to 3.5% nickel, 4 to 6% molybdenum and 0.25 to 0.85% vanadium.
