Abstract

1311104 Low carbon steel HOESCH AG 14 May 1970 [20 June 1969] 23491/70 Heading C7A Non-alloyed steel containing less than 0À015% C, up to 0À25% P, and when required for de-oxidation up to 0À5% Si and/or up to 0À1% Al is vacuum treated while molten and is then cast, hot-rolled, cold-rolled and de-carburized during re-crystallization annealing to a carbon content of less than 0À01%. Annealing may be continuous at 750-1100‹C. or in a closed furnace at 650-950‹C. The steel may contain Mn up to 0À8% or up to 1À1% when P is less than 0À05%.
