A method for casting medium carbon, B/Ti steel product using compact strip processing or thin slab casting. The method can include providing a steel composition including boron and titanium and casting the steel composition into a slab having a thickness between about 25 and 150 mm. The slab can have a cast composition including about 0.23 to 0.30 wt. % carbon, about 0.0010 to 0.0050 wt. % boron, about 0.010 to 0.050 wt. % titanium, about 1.15 to 1.50 wt. % manganese, less than 0.35 wt. % silicon and a Ti/N ratio greater than 2.9. The amount of each element is provided based upon the total weight of the steel composition. The steel slab can be free from cracks and significant defects. Furthermore, the steel slab can be used for electric resistance welded (ERW) products.
