ASTM A308-99

1.1 This specification covers sheet steel in coils and cut lengths coated with lead-tin alloy (terne metal, see 3.2.3) by the hot-dip process. This material is commonly known as terne and is used where ease of solderability and a degree of corrosion resistance are desirable. It is especially suitable where resistance to gasoline is required. It may also be used for stamping where difficulties in drawing may be lessened by the coating, which acts as a lubricant in the die. The weight of coating, always expressed as total coating on both sides, may be specified in accordance with Table 1.

1.2 Material furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A 924/A 924M, unless otherwise provided herein.

1.3 Terne-coated steel is available in a number of designations, types, and grades.

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
