Abstract

Provided is stainless steel for oil wells which has excellent corrosion resistance at high temperatures and is capable of stably achieving a strength of 758 MPa or more. This stainless steel for oil wells contains in mass% 0.05% or less of C less than 1.0% of Si 0.01 1.0% of Mn 0.05% or less of P 0.002% or less of S 16 18% of Cr 1.8 3% of Mo 1.0 3.5% of Cu 3.0 5.5% of Ni 0.01 1.0% of Co 0.001 0.1% of Al 0.05% or less of O and 0.05% or less of N with the balance made up of Fe and impurities. This stainless steel for oil wells satisfies the following formula (1) and formula (2). Cr + 4Ni + 3Mo + 2Cu = 44 (1) Cr + 3Ni + 4Mo + 2Cu/3 = 46 (2) In this connection the contents (mass%) of corresponding elements are assigned to respective symbols of elements in formula (1) and formula (2).
