ASTM A599/A599M-99
(Specification)Standard Specification for Tin Mill Products, Electrolytic Tin-Coated, Cold-Rolled Sheet
Standard Specification for Tin Mill Products, Electrolytic Tin-Coated, Cold-Rolled Sheet
SCOPE
1.1 This specification covers cold-rolled steel sheet in coils or in cut lengths, tin-coated by electrodeposition. The product is commonly known as electrolytic tin-coated sheet, and is for applications that need good solderability, good surface appearance, and a degree of corrosion resistance. Tin-coated sheet is produced to various designations of tin coating, as outlined in Table 1.
1.1.1 Electrolytic tin-coated sheet is customarily available as commercial quality, drawing quality, drawing quality special killed, and structural quality which are fully described in Specifications A 366/A 366M, A 611, A 619/A 619M, and A 620/A 620M. The tin coating is available as unmelted or melted.
1.2 Limitations-This specification is applicable to orders in either inch-pound units (as A 599), which is supplied in thicknesses 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 624 [A 624M].
1.3 Unless the order shows the "M" designation [SI units], the product shall be furnished to inch-pound units. The values stated in either inch-pound or SI units are to be regarded as standard. 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 from the two systems may result in nonconformance with this specification.
