ABSTRACT:
High strength low carbon steels having good ultraworkability which comprises 0.01-0.3 wt % of C, below 1.5 wt % of Si, 0.3-2.5 wt % of Mn and the balance of iron and inevitable impurities. In the steel, a low temperature transformation product phase consisting of acicular martensite, bainite or a mixed structure thereof is uniformly dispersed in a ferrite phase in an amount by volume of 15-40%. Wire articles of these steels and methods for making the steels are also disclosed.
