The steel core has since been largely done away with. Cheap AK47 Ammo. Todays 7.62×39mm is available in a variety of options. Several European manufacturers offer the caliber with a steel casing and Berdan primer, which at once makes it far more economical than any brass cased round. There are drawbacks to steel cased rounds, however.
ASTM A36 Carbon Steel vs. ASTM A572 Grade 50 ::May 30, 2020 · Both ASTM A36 carbon steel and ASTM A572 grade 50 are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common. For each property being compared, the top bar is ASTM A36 carbon steel and the bottom bar is ASTM A572 grade 50.

MA TINGS - Quaker Chemical CorporationThe American Iron and Steel Institute (AISI) tested many alloys and compared the normal cutting speed, tool life and surface finish to that obtained when machining B1112. Materials with scores above 1.00 are easier to machine than B1112. Likewise, materials with scores of less than 1.00 are more difficult to machine.
