Abstract
A roller of a rotary type compressor is made of an iron base alloy essentially consisting of 2.0 to 3.9% carbon, 2.0 to 3.0% Si, 0.3 to 1.0% Mn, up to 0.10% S, more than zero and not more than 0.50% V, 0.3 to 1.0% P, 0.01 to 0.5% Sb, and balance of Fe and incidental impurities. Preferably, the iron base alloy further includes 0.001 to 0.5% B. This roller is suitable when hydrofluorocarbon is used as a refrigerant.
