Abstract: In a chain saw unit, composed of a saw chain and saw chain bar, for a motor-driven wood-cutting chain saw, longer working life and other desirable results flow from forming one or both of its components from a low alloy steel having a carbon content of 0.55 - 0.75 wt. percent, and containing silicon and chromium in controlled small amounts. The alloy may contain, also, small amounts of one or more of the alloying metals, Mo; W; Mn; V; Al and Ni. After the component is formed it is hardened, preferably, austempered.
