Development of a New Type of Chromium Modified Steel
Original language description
The article outlines the development and verification of properties including the long-term creep strength of a new type of creep resistant chromium modified steel, which target material characteristic is 150 MPa of creep rupture strength at 650 °C and that will find application in a pressure system of newly-built power plants (ultra-supercritical boilers). The development of this steel was initiated under the CRESTA project, where two modifications of chemical composition were set up in order to obtain either a steel without Z-phase or a steel with the modified Z-phase based on tantalum. Experimental melts were made and their properties and structure were analyzed in a comprehensive manner, including long-term creep tests. At the same time, filler metals and welding processes were developed, too. The prospective results achieved under the project CRESTA are at present (2014-2018) followed-up by the project CRESTA 2, funded by the European Research Fund for Coal and Steel (RFCS).
