ASTM A599 / A599M

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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. 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.

TABLE 1 Electrolytic Tin-Coated Sheets Coating Weight [Mass]

Note 1???Listed below are the commonly produced coating weights [mass] upon agreement between the producer and the purchaser. Other combinations of coatings may be specified and the appropriate minimum average test values^A apply.

Designation No.	Nominal Tin Coating Weight [Mass] (Each Surface) lb/base box (g/m²)^B	Minimum Average Coating Weight [Mass] (Each Surface Test Value) lb/base box (g/m²)^B^, ^C
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)

^A Refer to Specifications A623 and A623M.

^B A base box is defined as a unit of area equivalent to 112 sheets 14 in. by 20 in. or 31 360 in.² (refer to Specification A623).

^C The minimum single spot value shall not be less than 80 % of the minimum average tin coating weight [mass] (see 8.1 and 8.2).

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 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
