Pressure vessel and boiler quality steel are commonly found throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. The companies in these industries set the highest demands in terms of quality, testing and conditions of supply, and we have all the necessary expertise to meet these demands.
In recognition of the increasing need for pressure vessel steel plate to demonstrate HIC Resistant properties. Our product is also particularly suited for pressure equipment where wet H2S corrosion can be a problem.
Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchanges and any other vessel that contains a gas or liquid at high pressures.
Familiar examples include gas cylinders for cooking and for welding, oxygen cylinders for diving and many of the large metallic tanks that you see in an oil refinery or chemical plant.

The manufacture of pressure vessels is tightly regulated as a result of the risks involved and as a consequence the materials that can be used in vessels is also tightly specified. The most common specifications for pressure vessel steels are the EN10028 standards – which are European in origin – and the the ASME/ASTM standards which are from the US.
Our strength is in the very high specification pressure vessel steel plate used in the oil and gas industry and specifically in steel plate resistant to Hydrogen Induced Cracking (HIC).

Product Specification

Available Grade:

ASME SA516 grade introduction:
SA516 grade 55, SA516 grade 60, SA516 grade 65, SA516 grade 70. These 4 grades are mainly defined by their different tensile and yield strength range, which is influenced by content of Carbon. For example sa 516 grade 70 has the highest tensile and yield strength range due to the highest Carbon content(up to0.28%). For higher grade like sa516 gr-70 steel plate, preheating might be needed for metal arc welding process, especially with thick steel plate.
Delivery State:
SA516-70n refers to normalized steel plate product, for steel plate and sheet thinner than 40mm we normally supply them as rolled-Steel Coil. Plates with thickness above 40mm are supplied normalized. SA516 grade 70 steel plate density is 0.284 cu/in3 (7861 kg/m3).
Mild test:
ASME SA 516-carbon steel plates are manufactured with mill certification following EN10204 3.1 or EN10204 3.2 standard version.
Inspection: MOODY SGS BV GL DNV ABS LIOYD’S Test: X-ray, UT, magnetic particle, inspection.
