Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 This material is considered as single-clad or double-clad nickel or nickel-base alloy clad steel plate, depending on whetherone or
17、 both sides are covered.3.1.2 The term plate as used in this specification applies to material 316 in. (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. Ordering Information4.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under thisspecification. Such requireme
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. Specify whether applicable to the cladding alloy, backing steel, or both (see Section 10).4.1.7 Mechanical Properties (see Sections 7, 13, a
22、nd 14).4.1.8 Restrictions, if required, on repair by welding (see Section 14).4.1.9 Additions to the specification or special requirements. requirements such as applicable construction code rules.4.1.10 Corrosions tests, if required.4.1.11 Notification when the cladding alloy is to be used for inclu
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

28、l be made by the open-hearth, electric-furnace (with separate degassing and refining optional), orbasic-oxygen processes, or by secondary processes whereby steel made from these primary processes is remelted using, but notlimited to electroslag remelting or vacuum arc remelting processes.5.1.2 The c
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. Chemical Composition6.1 The composite plate may conform to any desired combination cladding metal and base metal as described in 6.2 and 6.3,and as agreed upon between the purchaser and the manufacturer.6.2 Cladding MetalThe nickel or n
