Oregon was determined to find the highest-quality raw material to deliver optimum performance in all cutting conditions. After extensive metallurgical research, experimentation and field testing, a new alloy was created, soon establishing itself as the state-of-the-art in the saw chain industry.

All Oregon professional and harvester saw chains are now made from the company's own patented OCS-01 steel alloy. Designed to be more durable in cold weather conditions, Oregon cutting saw chain steel is tested and proven to be 125% tougher at minus 20° Fahrenheit and 20% tougher at room temperature.
