(2.73 mm) and over in thickness, and over 10 in.(254 mm) in width.3.1.3 alloy claddingthe nickel or nickel-base alloy component of the composite plate.3.1.4 base metal (backing steel)component to w

18、hich the alloy cladding is applied, usually the greater percentage of thecomposite plate and usually consisting of carbon or low-alloy steel.3.1.5 integrally and continuously bondedthe process by which the alloy cladding and base metal are brought together to forma metallurgical bond at essentially

19、the entire interface of the two metals by means other than those processes that do not producea homogeneous composite plate.4.

20、nts may include, but are not limited to the following:4.1.1 Quantity (weight or number of pieces).4.1.2 Heat treatment, if required (see Section 5).4.1.3 Dimensions, including the thickness of the cladding alloy and the backing steel, or of the total composite plate and if moreor less restrictive th

21、ickness tolerances apply.4.1.4 Cladding alloy specification (see Section 6).4.1.5 Base metal specification (see Section 6).4.1.6 Product analysis, if required.

23、sion in the design strength calculations for an applicableconstruction code.NOTE 1Construction codes may dictate certain fabrication requirements when the cladding is used in the design calculations that may be differentthan if the cladding is used for corrosion resistance only. This may be particul

24、arly important when the alloy cladding involves the use of weldedcomponents in the explosion bonded clad manufacturing process. It is incumbent on the purchaser to make the clad manufacturer aware of any suchrestrictions or applications at time of order.4.2 In addition to the basic requirements of t

29、ladding metal may be metallurgically bonded to the base metal by any method that will produce a clad steel that willconform to the requirements of this specification.5.1.3 For explosively bonded products, the alloy cladding metal may be comprised of two or more separate alloy plates or sheetscomplet

30、ely welded together to form a single fabricated component.5.2 Heat TreatmentUnless a specific heat treatment is required by the cladding material or base steel specification, or unlessotherwise agreed upon by the purchaser and manufacturer, the clad plate shall be furnished in a condition that is ap

31、propriate forthe cladding alloy, base metal, or both.A265 1226.
