Embodiments of the present disclosure comprise carbon steels and methods of manufacture. In one embodiment, quenching and tempering procedure is performed in which a selected steel composition is formed and heat treated to yield a slightly tempered microstructure having a fine carbide distribution. In another embodiment, a double austenizing procedure is disclosed in which a selected steel composition is formed and subjected to heat treatment to refine the steel microstructure. In one embodiment, the heat treatment may comprise austenizing and quenching the formed steel composition a selected number of times (e.g., 2) prior to tempering. In another embodiment, the heat treatment may comprise subjecting the formed steel composition to austenizing, quenching, and tempering a selected number of times (e.g., 2). Steel products formed from embodiments of the steel composition in this manner (e.g., seamless tubular bars and pipes) will possess high yield strength, e.g., at least about 165 ksi, while maintaining good toughness.

Sucker rod connection with improved fatigue resistance, formed by applying diametrical interference to reduce axial interference
A sucker rod connection is disclosed. The sucker rod connection comprises a tapered male member including a plurality of trapezoidal threads, and, a tapered female member also including a plurality of trapezoidal threads, in which the male member is capable of being received in threaded engagement with the female member, wherein the threads of the male member are in flank-to-flank contact, both flanks on each thread, with the threads of the female member, thereby creating diametrical interference between the male and female members preventing disengagement and substantially reducing axial interference between the male and female members.
