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 steels for pressure purposes (boilers, steam boiler plants, pressure vessels, etc.) at elevated temperatures
- Cu + Ni + Cr + Mo ≤ 0.70 %
- Al/N ≥ 2
- Tensile test values apply to "transverse" test pieces
- The tensile test for proof strength at elevated temperature is carried out on request.
- Impact test is not carried out for thickness thinner than 6 mm.
- Depending on agreement the impact energy can be specified as 40J in the purchase order.
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.
