摘要

研究了5种材料在NACE溶液和人工海水溶液中的氢致开裂(Hydrogen-induced cracking,HIC)行为,结果表明:当材料中存在硫化夹杂物时,氢致开裂敏感性增大.为了提高材料的抗氢致开裂性能,应控制其含量与形态.对于更恶劣的腐蚀环境(酸性油气),管线钢抗HIC的评价应采用NACE标准进行氢致诱导开裂试验.

Abstract

The behaviour of hydrogen-induced cracking(HIC)of five kinds of steels was investigated in NACE solution.The experimental results show that the sensibility of HIC is increased with sulfides.The amount and distribution of sulfides should be controlled to improve the HIC resistance of steels.
