Standard Specification for Tin Mill Products, Electrolytic Tin-Coated, Cold-Rolled Sheet
ABSTRACT
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.
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 steel (CS); drawing steel (DS); deep drawing steel (DDS); extra deep drawing steel (EDDS), and structural steel (SS). 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 0.036 in., or SI units [as A 599M], 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 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.
