ST44 Black Sheet

What is ST44 Mild Sheet?

ST44 Quality SheetRectangular section semi-product, which is called slab and formed as a result of solidification of liquid steel by continuous casting technique, is produced in hot rolling mills.hot rollingandand thicknesses obtained with1.50 - 20,00 mmin the form of rolls or sheets varying in the range ofis flat steel.

ST44 QualitySac Blacksheet metal hot rollingproduced byare flat steels. 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.Your black sheetsThe usage areas are very wide.
