    Abstract: This paper analyzed and studied the cause and mechanism of hydrogen brittleness and stress corrosion cracking of high stress part of GCr15 steel, and the corrosion electrochemistry action caused by the asymmetry of structure and stress and impurity under the condition of acidity and alkalescence and katalyst. In order to prevent from the hydrogen brittleness and stress corrosion cracking of high stress part of GCr15 steel, 7 technology measures were taken.

    Keywords:Stress; Hydrogen Brittleness; Stress Corrosion Cracking; Coordinated Effect.
