scope:

This specification covers the strand cast process for manufacturing hot-rolled carbon and alloy steel for projectile applications. The requirements of this specification supplement existing material specification requirements on individual projectile metal parts drawings when the steel being furnished is made by the strand cast process.

Strand casting process, equipment and reduction ratios shall be in accordance with the following classes and types as specified (see 6.2):

Class I - Steel made using submerged ceramic shrouding from tundish to mold. Class II - Steel made using a centrifugal caster. Class III - Steel made using either submerged ceramic shrouding or gaseous type shrouding from tundish to mold. Type A - Steel rolled to a 4 to 1 minimum reduction ratio. Type B - Steel rolled to a 2.5 to 1 minimum reduction ratio.
