1、Designation: A 599/A 599M 07Standard Specification forTin Mill Products, Electrolytic Tin-Coated, Cold-RolledSheet1This standard is issued under the fixed designation A 599/A 599M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, th
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. Scope*1.1 This specification covers cold-rolled steel sheet in coilsor in cut lengths, tin-coated by electrodepositi
3、on. 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-coa
4、ted 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 (
5、as A 599), which is supplied inthicknesses from 0.015 in. to 0.036 in., or SI units asA599M,which is supplied in thicknesses from 0.381 mm to 0.914 mm.For thicknesses lighter than 0.015 in. 0.381 mm, refer to A624 A 624M.1.3 Unless the order shows the “M” designation SI units,the product shall be fu
6、rnished 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
7、 from the two systems may result in noncon-formance with this specification.2.

10、cific to This Standard:3.1.1 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 discol
11、oration, is ahazard. Excessive 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 R

20、ucer.3.3 melted tin coatingtin coated by electrodeposition on abase steel normally having a ground-roll finish (see 3.2), andthen 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 reducin
21、g theamount of free tin available. Due to the limitations of thereflow section of the plating lines, certain thicknesses may notbe available with a melted finish.3.4 oilan extremely thin oil film furnished on both sur-faces of tinned sheet to minimize abrasion in shearing, coilingor uncoiling, shipp
22、ing, and handling. Usually dioctyl sebecate(DOS) or acetyl tributyl citrate (ATBC) is used. Surface activeagents such as glycerol 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
23、drawing lubricant.3.5 unmelted tin coatingtin-coated by electrodepositionon a base steel normally having a dull, blasted-roll surfacetexture (see 3.2).
