(Specification)Standard Specification for Stainless Chromium-Nickel Steel-Clad Plate
Standard Specification for Stainless Chromium-Nickel Steel-Clad Plate
ABSTRACT
This specification covers the requirements for plate of a carbon steel or low-alloy steel base to which is integrally and continuously bonded on one or both sides a layer of stainless chromium-nickel steel for pressure vessel. The steel shall be made by the open-heart, electric-furnace, or basic-oxygen processes and the alloy-cladding metal shall be metallurgically bonded to the base metal. The steel clad plate shall be heat treated. The steel specimens shall undergo tension test and shall conform to the required values of tensile strength and yield strength. The steel materials shall also undergo bend tests and shall conform to the required values of shear strength and bond strength. Product and chemical analyses shall also be performed on the steel specimens.
SCOPE
1.1 This specification2 covers plate of a carbon steel or low-alloy steel base to which is integrally and continuously bonded on one or both sides a layer of stainless chromium-nickel steel. The material is generally intended for pressure vessel use.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1 Definitions of Terms Specific to This Standard:
3.1.1 This material is considered as single-clad or double-clad corrosion-resisting chromium-nickel steel plate, depending on
whether one or both sides are covered.
3.1.2 alloy cladding—the stainless chromium-nickel steel component of the composite plate.
3.1.3 base metal (backing steel)—component to which the alloy cladding is applied, usually the greater percentage of the
composite plate and usually consisting of carbon or low-alloy steel.
3.1.4 integrally and continuously bonded—the process by which the alloy cladding and base metal are brought together to form
a metallurgical bond at essentially the entire interface of the two metals by means other than those processes that do not produce
a homogeneous composite plate.
