The correct answer is: Blackheart cast iron.

Blackheart cast iron and steel share similar properties, such as:

1. Strength: Both have high tensile strength.
2. Hardness: Both are relatively hard.
3. Ductility: Both can be machined and shaped.
4. Corrosion resistance: Both can be protected with coatings or surface treatments.

Blackheart cast iron is a type of cast iron that has been heat-treated to produce a machinable, ductile material with properties similar to steel. It is often used as a substitute for steel in certain applications.

Whiteheart cast iron, on the other hand, is a type of cast iron that has been heat-treated to produce a soft, ductile material with a high carbon content. It is not as strong or hard as blackheart cast iron or steel.

Therefore, only blackheart cast iron displays properties similar to those of steel.

Then blackheart cast iron shares some properties with steel, it is not identical and may have different applications and uses.
