Niobium Bearing Low Carbon Low Alloy(LCLA)value-added S355 structural steels reduces the overall material and construction costs for many high strength construction steel and heavy equipment applications.The recent development of the Nb-LCLA Approach is a value-added low cost approach for many structural steel applications including windtower supports,beams and other structural plate applications.Case examples are presented from Brazil,China and the USA.These Nb-bearing steels at lower carbon content compared to the traditional higher carbon normalize heat treated grades are more cost effective and reduce structural fabrication time through improved weldability as well.
