Improvement of 10B33 annealing-free performance by TMCP
The cold heading steel 10B33 for automobile was rolled by on-line low temperature large deformation and on-line heat preservation through controlled cooling technology,the pearlite group is small and dispersed,its hard-ness is obviously lower than that of the conventional wire rod,the section shrinkage rate is increased,and the cold workability is obviously improved,reduce process cost effectively.
