ASTM A353 /A353M Standard Specification for Pressure Vessel Plates, Alloy Steel, 9 Percent Nickel, Double-Normalized and Tempered1
1. ASTM A353/A353M  Scope
1.1 This specification2 covers 9 % nickel steel plates, double-normalized and tempered, intended particularly for welded pressure vessels for cryogenic service.
1.2 Plates produced under this specification are subject to impact testing at −320°F [−195°C] or at such other temperatures as are agreed upon.
1.3 The maximum thickness of plates is limited only by the capacity of the material to meet the specific mechanical property requirements; however, current mill practice normally limits this material to 2 in. [50 mm] max.
1.4 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.
1.5 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.

ASTM A353/A353M Heat Treatment
5.1 All plates shall be heat treated in accordance with 5.2. Shell plates and other parts, including heads and reinforcing pads, which are heated for forming, shall be heat treated after forming in accordance with 5.2.
5.2 Heat Treatment Procedure:
5.2.1 First Normalizing Treatment—Heat the plate to a uniform temperature of 1650 6 25°F [900 6 15°C], hold at this temperature for a minimum of 1 h/in. [2.4 min/mm] of thickness, but in no case less than 15 min, and cool in air.
