ASTM A516-70 Plate As Rolled

ASTM A516 Grade 70 Plate is also called out as ASME SA516-70.  This steel plate grade is a medium carbon alloy that also contains amounts of manganese, phosphorus, sulfur, and silicon. A516 is primarily used for service in welded pressure vessels where improved notch toughness is required. It is typically found in moderate and lower temperature applications. A516 is sometimes called PVQ516.

Supplementary testing such as Charpy Impacts, Ultrasonic Examination and Carbon Equivalency are available. All plates over 1-1/2″ Thick are required to be normalized.  A516 is the most popular Pressure Vessel grade of steel plate in the industry. It is produced in grades 55, 60, 65 or 70.  The most common is Grade 70 or called out A516-70.

ASTM A537 Class 2 Pressure Vessel Steel Plate

ASTM A537 Class 2

ASTM A537 Class 2 steel is a higher yield and tensile strength material used in the fabrication of pressurised vessels and steel boilers.

The steel includes the alloying of carbon, manganese and silicon and is heat treated using the quenched and tempered method which gives the material its residual strength. Sourced by the world’s leading fabricators, ASTM A537 Class 2 is a material used extensively by the oil, gas and petrochemical industry.

We will supply ASTM A537 Class 2 plates from stock or directly from the mill. We also offer steel cutting services including CAD based flame cutting to cut your steel into particular shapes.

Applications:

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 we also available ex–stock. We are particularly suited for pressure equipment where wet H2S corrosion can be a problem.

ASTM A537 Class 1 Pressure Vessel Steel Plate

ASTM A537 Class 1 carbon steel plates are engineered to be used in pressure vessel applications.

Applications of ASTM A537 Class 1 Carbon Steel Plate  

The material is a normalized steel which is heat treated and as a consequence displays greater yield and tensile strength than the more standard ASTM A516 grades. The steel is ideal for use in pressurized service both in boilers and pressure vessels and we supplies A537 Class 1 plates to the world’s leading fabricators who in turn serve the Oil, Gas and Petrochemical industry.
