Toughness of a metal
In materials science and metallurgy, toughness is the ability of a material to absorb energy and plastically deform without fracturing. Toughness is the strength with which the material opposes rupture. One definition of material toughness is the amount of energy per unit volume that a material can absorb before rupturing. This measure of toughness is different from that used for frac… WebMelting Point of Ductile Cast Iron – ASTM A536 – 60-40-18. Melting point of ductile cast Iron – ASTM A536 – 60-40-18 steel is around 1150°C. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs.
