ASME SA537 Class 1 Carbon Steel Plates PVQ Steel

ASME SA537 Class 1 carbon steel plates are produced for use in pressurised service and are commonly used in the fabrication of industrial pressurised vessels and boilers.


Class 1 plates are provided in normalised condition and are heat treated – as a result, the material displays greater yield and tensile strength than the more standard ASTM A516 grades. GNEE supplies ASME SA537 Class 1 plates to the world’s leading fabricators serving the Oil, Gas and Petrochemical industry. The material is used in a variety of applications including pressurised tanks and heat exchangers.
