Investigation of the Relationships between Material Properties and Processing Parameters of Boron Micro-Alloyed Quenched and Tempered Steels

摘要

The boron micro-alloyed quenched and tempered steels, contrary to their lower carbon content, are perfectly applicable for the manufacturing of steels having good wear resistance, strength and toughness. The manufacturing properties of steel, thanks to its lower carbon content, are better than that of low alloyed quenched and tempered steels to be replaced by them. The presentation covers the history of the introduction and production of the boron steels used in our country with special view on the experiments of DUNAFERR Company Group. Starting with factual examples, it comparises local and European-made products used for similar purposes regarding the European and national standardisation. Finally, it is alleging the most recent research activities of the company group to wider its production range of boron micro-alloyed quenched and tempered steels.
