Malleable Cast Iron. Malleable iron starts out as white iron casting but is then treated at a heat of roughly 1,650°F, 900°C. Malleable iron contains more blunt boundaries opposed to flakes, which eliminates the stress concentration problems that grey cast iron can cause. Malleable iron has properties that are very similar to mild steel.
