Analýza materiálu P355QH1 (1.0571)

Abstract

Steel production passed complicated development. By perfection and development of industrial processes a rise of wide assortment and steel types of steel were reached. One of the most effective technologies of steel production is continual steel casting. This process of produce is mainly used in steel produce, of the most demanded steel grade type at present. The P355QH1grade is part of the same group. Thanks the properties and numerous application possibilities this steel type is very demanded material especially for building and automative industry, agriculture and other branches. Custamer demands material of high quality. Material must be without surface defects including all metallographic analyses. In the experiment part of diploma work results of metallographic evaluations of the material P355QH1 grade are presented.
