Beschreibung
Zusammenfassung:	This invention provides a composition, and a threaded connection for pipes or tubes (1) that includes a lubricant coating layer (21) formed from the composition. The composition according to the present embodiment is a composition for forming a lubricant coating layer (21) on a threaded connection for pipes or tubes (1), and contains Cr2O3, a metal soap, a wax and a basic metal salt of an aromatic organic acid. The threaded connection for pipes or tubes (1) according to the present embodiment includes a pin (5) and a box (8). The pin (5) and the box (8) each include a contact surface including a threaded portion (4), (7) and an unthreaded metal contact portion. The threaded connection for pipes or tubes (1) includes, as an outermost layer, a lubricant coating layer (21) formed from the aforementioned composition on at least one of the contact surfaces of the pin (5) and the box (8).
