ASME SA 387 GRADE 22 Class 1 steel

ASME SA 387 GRADE 22 Class 1,SA387 Grade 22 Alloy Steel Plates Class 1 Plates
We supply plates to global fabricators serving the oil, gas and petrochemical industry. 
These industries require a pressure vessel grade steel which works well in elevated temperatures and our material serves this purpose well. And with good corrosion and oxidation resistance, SA387 Grade 22 Class 1 plates are a good option for sour gas environments too.
