2017-4-10NIOBIUM IN CAST IRON Introduction and Definitions The limit between wrought iron steel and cast iron is at about 2 carbon. Above this limit eutectic graphite or cementite are precipitated as can be seen in the iron-carbon two-phase diagram Figure 1. Iron with such high carbon content exhibits a relatively low melting point of about
