摘要： Disclosed is a lubricant composition for hot forming which contains 10-40 mass% of a solid lubricant, 5-20 mass% of a water-dispersible synthetic resin, 0.5-5 mass% of an amine salt of an inorganic acid, and 45-80 mass% of water. Such a lubricant composition for hot forming exhibits lubricating properties without being separated or washed away by roll cooling water at temperatures not less than 80˚C, while it does not have water resistance at temperatures less than 40˚C and thus can be easily cleaned away by water.

摘要： A rolling control method for a mandrel mill, a rolling control device, a control program, and a seamless tube. In the method, the press-down position of a first hole type rolling roll disposed on a finish stand (#i) is displaced outward when a raw tube (S) is rolled on the finish stand (#i) among stands forming the mandrel mill (M). Also, the press-down position of a second hole type rolling roll disposed on an upstream side stand (#(i-2)) is displaced outward when a raw tube is rolled on the upstream side stand (#(i-2)) with the same press-down direction as the finish stand (#i) positioned nearest the finish stand (#i). Accordingly, when the seamless tube is manufactured by using the mandrel mill, a part or all of the end part of the raw tube can be accurately rolled to a specified thickness.

摘要： The delayed fracture occurring after the hot working of a martensitic stainless steel is prevented by, after the hot working and prior to an heat treatment in which a quenching from a temperature equal to or higher than an Ac1 temperature of the steel is carried out, subjecting the martensitic stainless steel to a pre-softening heat treatment under such conditions that a softening parameter (P) defined by the following formula is 15,400 or more and a softening temperature (T) is lower than an Ac1 temperature of the steel: P (softening parameter) = T(20 + log t) wherein T: softening temperature [K] t: softening time [Hr]. This method is particularly effective for a martensitic stainless steel having such a steel composition that the amount of effective solid solution C and N (C* + 10N*) calculated by the following formulae is more than 0.45: C* = C - [12{(Cr/52) x (6/23)}/10]; and N* = N - [14{(V/51) + (Nb/93)}/10 - [{(Ti/48) + (B/11) + (Al/27)}/10].

摘要： A solid lubricating coating formed on a contact surface of a threaded joint for pipes has a matrix of a lubricating oil-containing polymer. The lubricating oil-containing polymer has either a uniform composition or a gradient composition in which the concentration of lubricating oil decreases towards the contact surface and in which there is substantially no lubricating oil in the vicinity of the contact surface.
