Optimization of Quenching Process In Hot Press Forming of 22mnb5 Steel For High Strength Properties

This paper presents hot press forming of 22MnB5 steel blanks for high strength automotive components. The hot press forming was performed using Schenck press PEZ0673 machine with maximum press force of 1000 kN. Samples were square 22MnB5 blanks, of 50×60 mm dimension. A high temperature furnace was...
