description: The work is devoted to studying influence of technological parameters of highstrength low alloy pipe steels manufacturing on steel mechanical properties and microstructure. The problems were solved:
1. Studying of influence of carbon, manganese, niobium and vanadium on mechanical properties of the steels;
2. Studying of influence of prerolling and hot rolling temperatures on mechanical properties of the steels and microstructure formation;
3. Studying of influence of accelerated cooling parameters on mechanical properties of the steels and microstructure formation;
4. Description of optimal pipestrips manufacturing modes for the steels.
The work was fulfilled on the premises and equipment of PJSK âSeverstalâ, which included experimental strips manufacturing and testing. Results were structured, tendencies of influence of technological parameters on experimental strips properties and microstructure were found. Based on the tendencies technological conditions were suggested for strips manufacturing using the steels with required properties of quality.
