Abstract: 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.

Abstract: A post-yield hardened steel tube, particularly useful for creating slotted liners, for use in various applications in the oil and gas industries. The steel specifications meet the broad API 5CT standard, but the resulting slotted tube exhibits both enhanced slot-ability characteristics and superior thermo-mechanical characteristics in buckling resistance and localization resistance. A method of manufacturing a steel tube with substantial post-yield hardening behavior across a temperature range between room temperature and 350° C. while providing good slot-ability, comprising using a steel meeting the broad API 5CT standard but with very small quantities of sulfur, performing a standard hot rolling process followed by a specifically defined heat treatment cycle, so as to create a microstructure characterized either ferrite plus pearlite or a ferrite plus bainite-pearlite.

Abstract: A method for protecting a metal surface from galling and corrosion includes a step of providing a protective dry film on the metal surface. The film includes a solid lubricant and a conducting polymer, the conducting polymer having lubricant properties and being capable of binding the solid lubricant to the metal surface. Threaded metal joint surfaces coated with the film are capable of resisting galling under high pressure and high torque conditions, even after several fastening and unfastening operations or over a long period of time. Protection from corrosion is also provided by the film. The method and film are economical in that only a single layer of protective compound need be applied in order to provide metal surfaces with both lubrication and protection against corrosion, and problems such as removal or leakage, which are associated with protective compounds that use oils, are avoided.
