Abstract

Behavior to hydrogen damage caused by stress corrosion in a H₂S medium (SSC) and to intergranular corrosion (IGC) in different mediums, such as oxalic acid (C2H₂O₄-2H₂0), iron sulphate-50 % sulfuric acid [Fe₂(SO₄)₃-50 % H₂SO₄], nitric acid (HNO₃), copper sulphate-16 % sulfuric acid (CuSO₄-5H₂O-16 % H₂SO₄) and cooper sulphate-50 % sulfuric acid (CuSO₄-5H₂O-50 % H₂SO₄), is studied in an AISI 347 austenitic stainless steel stabilized with 0.61 mass % Nb and hot rolled to a seamless pipe with 273.1 mm in diameter and 18.2 mm in thickness.
