Experimental Study on Hot Bending of 22MnB5 Steel

Abstract:

Special V-shaped heat bending test was designed for 22MnB5 hot forming steel of different thicknesses. Blanks after heating 5 min at around 950°C to austenize fully were bended at different temperature conditions, and simultaneously the spring-back behavior and microstructure features of heat bending specimens were investigated. The result shows that 600-650°C temperature zone is optimal for bending forming and martensite texture transforming. Real hot forming anti-collision beams were produced at 600-650°C and comparison bending test was conducted to reveal more qualified mechanics at this temperature zone.
