“Cast iron is durable, but not unbreakable. Like glass, the properties that make cast iron hard also make it brittle,” according to The Cast Iron Collector. Subjected to impact, it “will break before it bends.” Cast iron is brittle and cannot be worked, hot or cold.

Is cast iron more durable than steel?

This clearly shows that mild steel is a better option than cast iron when it comes to ultimate tensile strength. However, cast iron has better compressive strength than mild steel. Due to this, it will have greater resistance against breaking under compression. This also makes it quite durable and ideal for rugged use.
