ABSTRACT:
A stronger, lighter sucker rod formed from cold-drawn medium to high carbon steel composed of three basic components which provide versatility in forming the sucker rod. A sucker rod is disclosed which is formed of machined, cold-drawn steel elements. The construction of the sucker rod significantly increases the resistance of the rod to metal fatigue and yields a rod which is smaller in diameter and lighter in weight than an equivalent strength rod made from hot rolled or heat treated steel metal stock.
