Abstract

En la presente se proporciona un tubo de acero inoxidable dúplex, sin costura, que posee una excelente resistencia a la corrosión y que tiene una pequeña diferencia entre su límite de elasticidad a la tracción axial y el límite de elasticidad a la compresión. La presente también pretende proporcionar un método para fabricar un tubo de acero inoxidable dúplex, sin costura. El tubo de acero inoxidable dúplex, sin costura, tiene una composición que comprende, expresado como % en masa: C: del 0,005 al 0,08%; Si: del 0,01 al 1,0%; Mn: del 0,01 al 10,0%; Cr: del 20 al 35%; Ni: del 1 al 15%; Mo: del 0,5 al 6,0%; N: del 0,005 a menos del 0,150%, y el resto es Fe y las impurezas incidentales. El tubo de acero inoxidable dúplex, sin costura, tiene un límite de elasticidad axial de 689 MPa o más, y una relación de 0,85 a 1,15 como una fracción del límite de elasticidad a la compresión axial al límite de elasticidad axial.Provided herein is a seamless, duplex stainless steel tube which has excellent corrosion resistance and has a small difference between its axial tensile yield point and the compressive yield point. It is also intended to provide a method of making a seamless, duplex stainless steel tube. The seamless duplex stainless steel tube has a composition comprising, expressed as% by mass: C: 0.005 to 0.08%; Yes: from 0.01 to 1.0%; Mn: 0.01 to 10.0%; Cr: 20 to 35%; Ni: 1 to 15%; Mo: 0.5 to 6.0%; N: 0.005 to less than 0.150%, and the remainder is Fe and incidental impurities. The seamless, duplex stainless steel tube has an axial yield point of 689 MPa or more, and a ratio of 0.85 to 1.15 as a fraction of the axial compressive yield point to the axial yield point.
