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.
Hot rolled unalloyed structural steels for manufacture of construction equipment, machines and various machine parts, general construction plates, road and railway vehicles
- Copper content shall be minimum 0.20 %, if copper-containing steel is specified in the purchase order.
- There is no requirement for manganese content in thicknesses thinner than 20mm.
- 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 1.35% by heat analysis
- Deoxidation method of this products is fully-killed. Minimum aluminium to nitrogen ratio is 2:1.
- Tensile test values apply to "transverse" test pieces
Flat / Plate
Heavy plate products are obtained by rolling semi-finished products with a rectangular cross-section (slab) produced by the continuous casting method to a specific temperature, with thicknesses ranging from 6.00 to 200.00 mm and widths ranging from 1000 to 3600 mm.

- For grade 3241 of thickness greater than 40mm, the min limit of silicon content is 0.15 %.
- Tensile test values apply to "transverse" test pieces
- For plate products, minimum elongation value is reduced by 2 points.
