Abstract: A lubricating coating composition in which at least one basic lubricant selected from a basic sulfonate, a basic salicylate, and a basic phenate is dissolved in a volatile solvent is applied to the frictional surface of a box and a pin constituting a threaded joint for oil well pipes. The composition may further contain one or more of a thermoplastic resin powder, another lubricant, and an extreme pressure agent. The surface roughness of the frictional surfaces preferably has an Rmax in the range of 5 - 40 micrometers.

Abstract: A composition for lubricating-film formation which comprises a base and dissolved therein at least one basic oil selected among basic sulfonates, basic salicylates, and basic phenates. The composition is applied to the frictional surface of a box and/or pin constituting a screw joint to form a lubricating film. The composition can further contain one or more of particulate thermoplastic resins, other oils, and extreme-pressure additives . The mating parts preferably have a surface roughness of 5 to 40 .mu.m in ter ms of Rmax.

Abstract: When a metal strip material is cold rolled, roll cross rolling and roll parallel rolling are combined, and rolling is carried out by the roll parallel rolling system at at least the final stand (in the case of a tandem mill) or in at least the final pass (in the case of a single-stand mill such as reverse mill) to obtain a rolled metal strip free from torsion and having excellent luster. In some cases, preliminary cold rolling of a rolling reduction of at least 5 % is in advance applied to a metal strip material by the roll cross system, and then cold rolling by the combination of roll parallel rolling or roll cross rolling and roll parallel rolling is carried out.
