Description

ASME SA387 Grade 22 Class 2

We supply ASME SA387 Grade 22 Class 2 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 2 plates are a good option for sour gas environments too.
