This guide covers standard specification for nickel steel plates, double-normalized and tempered, intended particularly for welded pressure vessels for cryogenic service. The steel shall be killed and shall conform to the fine austenitic grain size requirement. All plates shall undergo heat and product analysis and shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, and nickel. Tensile properties of the steel plate shall meet the specified values for tensile strength, yield strength, and elongation. The material shall undergo mechanical tests such as tension test and impact test.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers double-normalized and tempered 9 % nickel steel plates 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.
