    Abstract: The present invention concerns a high-temperature lubricant for the hot shaping of high-grade and carbon steels, which has a content of graphite, organic blowing agent and inorganic separation agent, and the use thereof. In order to provide a high-temperature lubricant which can be used for a wide range of steel qualities for different wall thicknesses to be rolled and stretching effects and which is moreover stable in respect of temperature, provides constant rolling results upon a change in the wall thickness and/or the quality of steel and does not lead to unwanted cementation of the rolled material, the high-temperature lubricant according to the invention contains at least the following constituents in percent by weight with respect to the solids content: (a) 40 to 90% by weight graphite, (b) 2 to 50% by weight organic blowing agent, and (c) 5 to 50% by weight inorganic separation agent, wherein the organic blowing agent (b) is selected from the group consisting of melamine, melam, melem, melon, phosphate salts and polyphosphate salts of the aforesaid compounds with phosphate chain lengths in the region of n=1 to 1000, reaction products and adducts of the aforesaid compounds with cyanuric acid or isocyanuric acid, and mixtures of the aforesaid, and the inorganic separation agent (c) is a sheet silicate or a mixture of sheet silicates.

    Abstract: A threaded joint for steel pipes comprises a pin (1) and a box (2) each having a threaded portion (3a or 3b) and an unthreaded metal-to-metal contact portion (4a or 4b) as contact surfaces which contact each other when the joint is fastened. The contact surfaces (3a and 4a and/or 3b and 4b) of at least one of the pin (1) and the box (2) are coated with a lower layer of a solid lubricating coating containing a solid lubricating powder (e.g., molybdenum disulfide, tungsten disulfide, or graphite) and a binder (e.g., an epoxy or other organic resin) and an upper layer of a solid corrosion protective coating formed by an organic resin which does not contain solid particles.
