Abstract
The deep-drawing property of a hot- and cold-rolled low carbon steel sheet is improved by a two-stage annealing process comprising a first preliminary anneal at 470-570 DEG C. for more than 30 minutes, e.g. in HNX gas (nitrogen containing by volume 3-10% hydrogen and 0.05% each of CO and CO2) to cause partial recrystallization with cube-on-corner grain orientation, then a final soft anneal at a higher temperature, preferably open coil annealing between 600 DEG C. and the Ac3 transformation point, under a decarburizing and denitriding atmosphere, e.g. of hydrogen and steam, to produce an anisotropic grain structure. The maximum C content of the steel is 0.04%; Si, Mn, S, P, Cu, Al and N may be present as impurities in the steel.
