Abstract
A low alloy nickel-manganese steel consists essentially of carbon 0.18-0.23 weight percent, manganese 0.70-0.90 weight percent, silicon 0.20-0.35 weight percent, chromium 0.40-0.60 weight percent, nickel 0.40-0.70 weight percent, molybdenum 0.15-0.25 weight percent and the balance iron. The steel is especially well suited for use as a backing material for bimetallic cylinders prepared by the centrifugal casting process. The backing material has improved stability at the temperatures employed during centrifugally casting a layer of a lining alloy within a cylinder of the backing material. The backing also has improved weldability and less tendency to develop residual bending stresses under the temperatures and pressures encountered during manufacture and use of the cylinder.
