(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.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
