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.

1.1 This specification covers plate, sheet, and strip of 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 the standard. SI units are provided for information only.
