More Information
Summary:TITLE OF THE INVENTION HIGH STRENGTH LOW CARBON STEELS, STEEL ARTICLES THEREOF AND METHOD FOR MANUFACTURING THE STEELS 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.
