6404 Quality Sheet Specification
Low-carbon unalloyed mild steels for cold reducing with the obligation of batch annealing
AlternativesThere is no alternative to this sheet.
Flat / Hot Rolled
Flat steel products are obtained by heating semi-finished products with a rectangular cross-section (slab), which are produced by the continuous casting method, to a specific temperature and then rolling them, with thicknesses ranging from 1.40 to 25.40 mm and widths ranging from 700 to 2025 mm, produceed as coil or by cutting/slit-coiling flat steel products from coils.
