Abstract
THE manufacture of bullet-proof steel is surveyed in an article by A. G. Arend in the Electrician of July 31. Formerly intended for helmets, bulletproof steel was also made for breastplates in the closing stages of the War of 1914-18. When the latter were first proposed, a manganese-vanadium steel was employed containing some 0-90 per cent of man- ganese and 0-20 per cent of vanadium, and was prepared in Heroult three-phase electric furnacess Despite the purest possible metal being produced, results were not uniform, and a manganese steel was substituted containing 12 per cent of manganese, and 1 per cent of carbon.
