Product Overview

Our SA516 Gr.60 / Gr.70, SA537 Cl.1 / Cl.2, P265GH, P355GH, P355NH / NL pressure vessel steel plates are widely recognized general pressure vessel carbon steel, manufactured to ASME and EN European standards. This series steel is designed for room and moderate low-temperature pressure equipment service.

SA516 series carbon steel plate is the most popular ASME pressure vessel grade, commonly used for welded pressure vessels, storage tanks, heat exchangers. SA537 is normalized carbon-manganese steel with improved toughness for thicker plate applications. P265GH, P355GH, P355NH and P355NL are EN standard boiler & pressure vessel steel grades, widely accepted across European chemical, energy and manufacturing industries.

These steel plates feature stable tensile strength, good ductility and outstanding welding property. All products come with full material test certificates, can perform UT, Charpy V-notch impact test upon request. We provide various thickness, width and length, support flame cutting, plasma cutting and machining according to customer drawings. Typical applications include industrial pressure vessels, chemical processing equipment, oil & gas storage tanks, power plant auxiliary vessels and other pressurized structural components.
