The Strength of Wrought Iron as Affected by Its Composition and by Its Reduction in Rolling #263057

But this increased tenacity and decreased ductility of the 1 in. Bar are not due to P. Alone; it had Si. Against Si. In. The larger bar, and it had more reduction in rolling. Phosphorus may thus accompany the highest general value; that this element did not cause inferior welding, may be inferred from the fact that iron px, made of the same materials and in the same way, except that one course of piling and hammering was omitted, welded much better, although its tenacity and ductility were decreased.
