INFORMATIONS ABOUT PROPERTIES OF THERMOMECHANICALY PROCESSED STEELS AFTER APPLICATION OF OTHER PRODUCTION PROCESSES

Abstract

This contribution deals with steels that have high-strength steels and with chosen technological properties in field of welding, mechanical working and machining. Practically by the mentioned cases it is necessary to take care, that by technological processing of the mentioned steels the temperature will not exceed, that could cause the degradation of the mechanical properties. This eventuality is most possible by welding and cutting materials like Armox and Hardox event. Weldox. The contribution shall be referred to the results of specific tests selected thermomechanical materials in terms of changes in their properties after welding in active gaseous shield. In this method the results of tests of basic mechanical properties by the tensile strength test, by the hardness test and the impact strength test are mentioned. In conclusion there are the results of specific test and the comparison of the strength characteristics of chosen processed steels.
