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.
Designation No. | Nominal Tin Coating | Minimum Average Coating |
5 (0.6/0.6) | 0.025/0.025 (0.6/0.6) | 0.02/0.02 (0.5/0.5) |
10 (1.1/1.1) | 0.05/0.05 (1.1/1.1) | 0.04/0.04 (0.9/0.9) |
15 (1.7/1.7) | 0.075/0.075 (1.7/1.7) | 0.06/0.06 (1.4/1.4) |
20 (2.2/2.2) | 0.10/0.10 (2.2/2.2) | 0.08/0.08 (1.8/1.8) |
25 (2.8/2.8) | 0.125/0.125 (2.8/2.8) | 0.11/0.11 (2.5/2.5) |
50 (5.6/5.6) | 0.25/0.25 (5.6/5.6) | 0.23/0.23 (5.2/5.2) |
75 (8.4/8.4) | 0.375/0.375 (8.4/8.4) | 0.35/0.35 (7.8/7.8) |
100 (11.2/11.2) | 0.50/0.50 (11.2/11.2) | 0.45/0.45 (10.1/10.1) |
1.2 Limitations—This specification is applicable to orders in either inch-pound units (as A599), which is supplied in thicknesses from 0.015 in. to 0.036 in., or SI units [as A599M], 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/A624M [A624M].
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.
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. The material shall conform to specified chemical composition requirements. The mechanical property requirements for structural steel, high-strength low-alloy steel with and without improved formability, commercial steel, and deep drawing steel are presented in details. The weight [mass] of coating shall conform to specified requirements fit for individual coating designations. The typical methods for determination of tin coating weights are described.
