ASTM B898-11

Standard Specification for Reactive and Refractory Metal Clad Plate

ABSTRACT
This specification covers plate consisting of a base metal to which is bonded, integrally and continuously, on one or both sides a layer of one of the following: titanium, zirconium, tantalum, niobium, and their alloys. The material generally is intended for pressure vessel use. The cladding metal shall be bonded to the base metal by any cladding operation that will produce a clad product which will conform to the requirements of this specification. When the cladding operation does not affect the chemical composition of the cladding or base metal, or both, the chemical analysis, in accordance with cladding, or base metal specifications or both, may be performed prior to the cladding operation. All heat treatments shall be performed as needed in the cladding operation unless otherwise specified or agreed between the purchaser and the manufacturer. Mechanical testing of the base metal, in accordance with the base metal specification, may be performed prior to the cladding operation. The tensile properties shall be determined by a tension test on the base metal only in accordance with the testing requirements of the base metal specification. The specimen orientation, location with respect to thickness, and number of tests and retests shall be in accordance with the requirements of the base metal specification when tension, bend, and impact tests shall be performed. The product surfaces shall be free of excess imperfections and extraneous materials as determined by visual examination.
SCOPE
1.1 This specification covers plate consisting of a base metal to which is bonded, integrally and continuously, on one or both sides a layer of one of the following: titanium, zirconium, tantalum, niobium, and their alloys. The material generally is 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. The values in parentheses and in metric tables are provided for information only.
