ASTM A353 / A353M
This specification covers double-normalized and tempered 9 % nickel steel plates intended particularly for welded pressure vessels for cryogenic service.Plates produced under this specification are subject to impact testing at −320°F [−195°C] or at such other temperatures as are agreed upon.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.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.

| 0.13 maxA | 0.98 | 0.015 maxA | 0.015 maxA | 0.13–0.45B | 8.40–9.60 |
Note: A Applies to both heat and product analyses.
Note: B The specified minimum limit does not apply if the total aluminum content is 0.030 % or more, or provided that acid soluble aluminum is 0.025 % or more.
