DUPLEX STAINLESS STEEL TUBE AND METHOD FOR PRODUCING SAME

摘要

A dual phase stainless steel pipe includes tensile yield strength YS LT of 689.1 MPa to 1000.5 MPa in a pipe axis direction of the dual phase stainless steel pipe, in which the tensile yield strength YS LT , a compressive yield strength YS LC in the pipe axis direction, a tensile yield strength YS CT in a pipe circumferential direction of the dual phase stainless steel pipe, and a compressive yield strength YS CC in the pipe circumferential direction satisfy all Expressions (1) to (4),
