SA387 Gr 22 Class 2 Plates
We provide plates to international fabricators that work in the petrochemical, oil and gas industries.
These industries call for pressure vessel grade steel that performs well at high temperatures, and our product excels in this regard. Additionally, SA387 Grade 22 Class 2 plates are an excellent option for sour gas situations due to their good corrosion and oxidation resistance.
