Abstract
A nickel-base alloy resistant to wear is disclosed. The alloy contains as its principal elements chromium, molybdenum, silicon, boron and carbon. The alloy, when composed of the elements in the proportions as taught, provides an outstanding combination of engineering properties including abrasive and adhesive wear, corrosion resistance, hot hardness and impact strength. This combination of properties is essential when the alloy is used in certain suggested forms including internal combustion engine parts, fluid valve parts, gas and steam turbine parts and chain saw guide components.
