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.

- These grades are produced in İsdemir facilities.
- When copper is requested in the chemical compositon, value specified in the table will be evaluated as minimum value. When copper is not specified, the copper limit is a maximum requirement.
- For each reduction of 0.01 percentage point below the specified max C an increase of 0.06 percentage point above the specified max for Mn is permitted up to a max of 1.50% by heat analysis
- V, Nb, Ti can be added seperately or in various combinations as indicated in the table.
