PRODUCT DESIGN AND PRODUCTION PRACTICE OF 700MPA HIGH STRENGTH HOT ROLLED STRIP FOR AUTO AXLE TUBE
According to the technical specifications of 700MPa high strength automotive axle tube steel,a low cost of 0.07%C+1.5%Mn+0.05%Nb+0.10%Ti was designed.The high strength mainly relies on grain refinement strengthening and precipitation strengthening.The recrystallization,precipitation,and CCT curves of the 700MPa grade axle tube steel were studied in order to determine a reasonable TMCP process.By controlling the low level segregation band,low level of C and N content,700MPa grade high strength automotive axle tube steel is successfully developed with excellent mechanical property,welding property,flattening and flaring property,torsion fatigue property,static torsional property and surface quality.
