Abstract

1334349 Alloy steel bar; heat treatment FRIED KRUPP HUTTENWERKE A G 21 June 1972 [24 June 1971] 29040/72 Heading C7A Steel bar containing in percentage by weight is hot rolled, cooled in air to form a bainitic structure, and is then either cold worked, as by stretching, and tempered at 100‹-400‹C. or is without working tempered at 150-550‹C. The bar is used particularly for concrete reinforcement.
