2、e year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers cold-rolled steel sheet in coilsor in cut lengths, tin-coated by electrodepositio
3、n. The productis commonly known as electrolytic tin-coated sheet, and is forapplications that need good solderability, good surface appear-ance, and a degree of corrosion resistance. Tin-coated sheet isproduced to various designations of tin coating, as outlined inTable 1.1.1.1 Electrolytic tin-coat
4、ed sheet is customarily availableas commercial steel (CS); drawing steel (DS); deep drawingsteel (DDS); extra deep drawing steel (EDDS), and structuralsteel (SS). The tin coating is available as unmelted or melted.1.2 LimitationsThis specification is applicable to ordersin either inch-pound units (a
5、s A 599), which is supplied inthicknesses from 0.015 in. to 0.033 in., or SI units as A 599M,which is supplied in thicknesses from 0.38 mm to 0.84 mm.For thicknesses lighter than 0.015 in. 0.38 mm, refer to A 624A 624M.1.3 Unless the order shows the “M” designation SI units,the product shall be furn
6、ished to inch-pound units. The valuesstated in either inch-pound or SI units are to be regarded asstandard. Within the text, the SI units are shown in brackets.The values stated in each system are not exact equivalents;therefore, each system must be used independently of the other.Combining values f
7、rom the two systems may result in noncon-formance with this specification.2.

10、.1.1 chemical treatmenta passivating chemical treat-ment, normally applied to the tinned surface to stabilize thesurface to control tin oxide formation and growth. Sodiumdichromate is most commonly used. Without such treatment,severe tin oxide growth, and its resultant discoloration, is ahazard. Exc
11、essive oxide growth may also cause poor solder-ability and poor adhesion of organic coatings. If a specialsurface treatment is required, it should be negotiated with thesupplier.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel, and Related Alloys and is th

18、 sheet.3.2.2.1 DiscussionIt is possible to produce either No. 5 orNo. 7 Finish as unmelted or melted; however, end applicationis important and should be negotiated with the producer.3.3 melted tin coatingtin coated by electrodeposition on abase steel normally having a ground-roll finish (see 3.2), a
19、ndthen melted to reflow the tin. The resultant coating has abrighter appearance than unmelted tin. An iron-tin alloy layeris developed during the melting operation, thus reducing theamount of free tin available. Due to the limitations of thereflow section of the plating lines, certain thicknesses ma

Usually dioctyl sebecate(DOS) or acetyl tributyl citrate (ATBC) is used. Surface activeagents such as gl
21、ycerol mono-oleate may be incorporated intothe lubricant for application on tinned sheet. Oil film other thannormal should be negotiated with the producer. The oil film isnot a drawing lubricant.3.5 unmelted tin coatingtin-coated by electrodepositionon a base steel normally having a dull, blasted-ro
