ST52 Sac
ST52 Quality Sheet Slab is a flat steel in roll or sheet form, the thickness of which varies in the range of 1.50 – 20.00 mm, obtained by hot rolling of the rectangular semi-product, which is formed as a result of the solidification of the liquid steel with the continuous casting technique, in the hot rolling mill. .
ST52 Quality Sheet Black sheets are flat steels produced by hot rolling. They are the most produced and consumed products in Turkey and in the world. Especially in developed and developing countries, its production and consumption is increasing every year. The usage areas of black sheets are very wide.
