ASME BPVC Section XII 2010

1.4 Bond integrity Class (1, 3, or 5), 4.1.5 Dimensions including the minimum or nominal thickness of the cladding alloy, and the backing steel, or of the total composite plate and if more or less restrictive thickness tolerances apply, SA-264 2007 SECTION II, PART A 4.1.6 Product analysis, if required (see Section 10). Specify whether applicable to the cladding alloy, backing steel or both, 4.1.7 Mechanical properties, including shear test if required,

4.1.8 Finish (see Section 12),

4.1.9 Restrictions, if required, on repair by welding (see Section 14),

4.1.10 Additions to the specification or special requirements, and 4.1.11 Corrosion testing if applicable. 4.2 In addition to the basic requirements of this specifi- 5.2.2 Duplex stainless steel clad plates shall be pro- vided in a heat treated condition as agreed upon between the purchaser and the manufacturer.

5.2.3 When plates are to be cold formed, or when otherwise required by the base metal specification, the purchaser may specify that such plates, following solution annealing, be heat treated for grain refinement of the base metal by normalizing and either air cooled or water quenched as appropriate. In the case of clad plate manufac- tured without hot rolling, the base metal and alloy cladding components may be heat treated separately as appropriate prior to bonding. cation and the backing steel specification, certain supple- 6.
