[0002] In oil and gas production, the presence of hydrogen sulfide compounds may cause cracking in steel, thus affecting the safety and reliability of equipment. Therefore, evaluating these cracking phenomena through a microscope can help engineers and scientists better understand the performance of materials and take corresponding preventive measures during design and use.

[0003] The purpose of HIC test is to evaluate the material's resistance to hydrogen-induced cracking under specific environmental conditions, which is crucial to ensure the safety of the material in an environment containing hydrogen.
