    Metallurgical Processes and Defects in Steel Products ce rolling steels

    Oct 10, 2016 · The common rolling defects of steels are given below. During the hot rolling, if the temperature of the steel is not uniform then the flow of the material occurs more in the areas having higher temperature and less in the parts with lower temperature. High temperature difference results into cracking and tearing.Defects / Hydrogen Cracks in Steels - Identification - TWIIn C-Mn steels, because there is a greater risk of forming a brittle microstructure in the HAZ, most of the hydrogen cracks are to be found in the parent metal. With the correct choice of electrodes, the weld metal will have a lower carbon content than the parent metal and, hence, a lower carbon equivalent (CE).A516 and A387 Pressure Vessel Steels: A Technical A516 and A387 Pressure Vessel Steels: A Technical Overview Introduction ArcelorMittal is the major producer of carbon and alloy plate for the petroleum, petrochemical and chemical processing industries in the United States.
