The ,carbon steels, of interest in this report are those with ,carbon, equal to or less than about 0.35% to facilitate welding. A further distinction can be made according to ,carbon, content. ,Low,-,carbon steels, (below 0.15% ,carbon,) contain too little ,carbon, to benefit from hardening and are
