Název v původním jazyce

Evaluation of production and properties of the forged bar made of super-duplex austenitic-feritic steel

Popis výsledku v původním jazyce

Design of technology for production of new material involves many research and development activities. The presented work is part of the proposal of chemical composition and technology for production of high alloyed steel. The proposal is realized with respect to the subsequent possibilities of material forming and to the requirements of potential customers. Specifically the steels with austenitic and ferritic structure, so called super-duplex stainless steels (SDSS) are studied. SDSS are more resistantto corrosion than austenitic steels. The proposal of production of ingot from the steel grade 1.4477 was prepared, followed by verification in the company MATERIAL & METALLURGICAL RESEARCH Ltd. (MMR). The ingot was then forged in conformity with the proposal at VÍTKOVICE HEAVY MACHINERY (VHM) into three rods. The forged rods with diameters of 250, 300 and especially 150 mm were after heat treatment subjected to mechanical tests. They were evaluated by hardness test, tensile strength and
