• Some Studies on the Sulphide Corrosion Cracking of Chromium-Molybdenum Steels (Report 1)

抄録

Recently, the problem in sulphide corrosion cracking of the LP gas plants has been studied vigorously in laboratories.<BR>But, the object of this study is related to high strength steels because these are used for constructing the LP gas plants.<BR>It is a familiar fact that Chromium-Molybdenum low alloy steels are superior in sulphide corrosion cracking to other high strength steels.<BR>But, generally it is recognized that Chromium-Molybdenum steels are poor in weldability.<BR>Authors hrve commenced this study to clear this sulphide corrosion cracking of 21/4% Cr-I% Mo weldmetal.<BR>The conclusions of this report are as follows.<BR>1. The embrittlement of this Chromium-Molybdenum steel in the solution of 0. 5% acetic acid saturated by hydrogen sulphide is regarded as the hydrogen-embrittlement.<BR>2. We can recover the majority percentage of this embrittlement by artificial aging in a short period of time.
