1. Sco Scope pe 1.1 This specification specification covers rolled steel structu structural ral shapes for use in building framing or bridges, or for general structural structural purposes.

4. Mater Materials ials and Manuf Manufactu acture re 4.1 The steel shall be killed, killed, and such shall be confirmed confirmed by   killed steel  on the test report, or by a report on a statement of  killed the presence of a sufficient quantity of a strong deoxidizing element, such as silicon at 0.10 % or higher, or aluminum at 0.015 % or higher.

1.2 Supplementary requirements are provided for use where additional testing or additional restrictions are required by the purchaser. Such requirements apply only when specified in the purchase order. 1.3 Whe When n the steel is to be wel welded ded,, a weld welding ing procedu procedure re suitable for the grade of steel and intended use or service is to be util utilized ized.. See App Append endix ix X3 X3 of Spe Specifi cificati cation on   A6/A6M for information on weldability.
