It should be heat treatment, such as normalizing the plate
Hydrogen-resistant steel plates exhibit excellent performance in tests related to hydrogen-induced cracking, as well as good resistance to hydrogen sulfide corrosion; they are primarily used in large-scale chemical and petroleum projects.
Hydrogen-resistant steel plates, which exhibit excellent performance in tests against hydrogen-induced cracking
I checked the manual on steels for pressure vessels, but I didn’t find this grade; it’s possible that the manual is a bit outdated.
Hydrogen-resistant steel plate, but it cannot be used at too high temperatures
What the people upstairs said is correct – hydrogen-resistant steel plates. It is generally written as “HIC”.
