Iron ore - Wikipedia

Bog ore often has a high phosphorus content (Gordon 1996, p. 57). The strength and hardness of iron increases with the concentration of phosphorus. 0.05% phosphorus in wrought iron makes it as hard as medium carbon steel. High phosphorus iron can also be hardened by cold hammering. The hardening effect is true for any concentration of phosphorus.
