    摘要： A pipe joint comprises a pair of tubular joint members (10,11), an annular gasket (13) interposed between opposed end faces of the two joint members, and threaded means for joining the two joint members. Each of the joint members is prepared from a stainless steel having a surface with a Vickers hardness of at least 300. The gasket is prepared from a stainless steel comprising, in ratio by weight, 12.90 to 15.00% of Ni, 16.50 to 18.00% of Cr, 2.00 to 3.00% of Mo, up to 0.02% of C, up 0.30% of Si, up to 0.40% of Mn, up to 0.03% of P, up to 0.003% of S, up to 0.25% of Cu and up to 0.01% of Al, the gasket having a surface with a Vickers hardness of 90 to 160.
