ASTM A553 Standard for Pressure Vessel Plates Alloy Steel
ASTM A553 Document Information: Standard Specification for Pressure Vessel Plates, Alloy Steel, Quenching and Tempering 8 and 9 % Nickel. ASTM A553 covers 8 and 9 % nickel alloy steel plates for use in the water quenched and tempered condition intended for the fabrication of welded pressure vessels.
Plates produced under this specification are subject to impact testing at −320°F [−195°C] for Type I, and −275°F [−170°C] for Type II or at such other temperature as are agreed upon. The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical properties requirements; however, current mill practice normally limits this material to 2 in. [50 mm] max.
This material is susceptible to magnetization. Use of magnets in handling after heat treatment should be avoided if residual magnetism would be detrimental to subsequent fabrication or service.
The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
For ASME Boiler and Pressure Vessel Code applications, see related Specification SA-553/SA-553M in Section II of that Code.
