摘　　要：１０００ｍ３Ｎ－ＴｕＦ５０钢制球罐，在使用中发生应力腐蚀现象，使球罐表面产生裂纹；裂纹形成后不断扩展，严重地威胁安全生产。通过检验与分析，探讨了裂纹的性质及形成的有关因素，为防止球罐应力腐蚀的发生和裂纹的修复提供了科学依据。Stress corrosion emerged in the 1000m 3N TuF50 steel storage sphere may develop a great deal of surface cracks,which need to be controlled to ensure safety in production.Factors effected the development,propagation and stability of the cracks are determined by defect detecting tests and theoretical analysis.This paper has provided a scientific basis for stress corrosion prevention and defects repair.
