What is the breaking point of iron?

The breaking point of iron, often referred to as its ultimate tensile strength, typically ranges from about 370 to 700 megapascals (MPa), depending on the specific type of iron and its treatment. Cast iron generally has a lower breaking point compared to wrought iron, which is more ductile and can withstand higher stress. Factors such as temperature, alloying elements, and manufacturing processes can significantly influence the breaking point.
