In the application of hot rolled steel sheets for automobile suspension and chassis parts, hole expansionability is required in addition to the strength since burring is frequently used. 'NANOHITEN' is a variety of precipitation hardened steels with ferrite single phase matrices and ultra fine carbides of single nanometer size, which lead to higher strength and excellent hole expansionability. 'BHT Steel' provides almost the same effect as higher strength steel because of the large increase of tensile strength based on the strain aging effect of N.
