The author shows the possibilities of using computer technologies to create databases and parameter selection algorithms, when choosing the steel grade. Now, the use of computer technologies for selecting and analyzing properties of engineering materials is the most common method for an optimal search for the required type and grade of machine steel. There are numerous foreign and Russian development results in this area of computer science, but foreign similar projects usually do not provide users with data on properties of materials in the CIS countries, in particular Russia, and most of development results of organizations and research centers in Russia are written in the form of steel grade guides and spreadsheets, preventing from using them fully for an algorithmic selection of materials. Work on creating and writing databases and selection algorithms for steel grades and engineering materials has been carried out at Alekseev Nizhny Novgorod State Technical University since 1995. Now, the STEEL software package for selecting a machine steel grade has been created and is applied. STEEL software is used by engineering companies and technical universities for engineering, scientific, marketing and educational purposes. Keywords Software package, grade selection, machine steel.
