Abstract

PURPOSE: To lower the heat-treating temperature of an antiabrasion 15Cr-3Mo special cast iron while keeping its excellent resistance to sand and earth abrasion, by adding a specified amount of Ni into the cast iron.
CONSTITUTION: A cast iron containing 2.0W4.0% C, 0.5W1.5% Mn, 0.3W1.5% Si, 10W20% Cr, 1W5% Mo and 1W3% Ni is used for the shaft-sealing device of the lower road wheel of a catapillar-type vehicle, e.g. a bulldozer or the like, instead of an antiabrasion 15Cr-3Mo special cast iron. The cast iron is excellent in resistance to sand and earth abrasion, and has a low heat-treating temperature such that a high hardness can be obtained by heat treatment from a low temperature of 850°C or so. Consequently, the cast iron is suitable as a ring-shaped cast article having a very thin wall, e.g. a floating seal or the like, which is expected to resist to deformation during the heat treatment.
