26 - Which of the following judgments is wrong for iron and carbon? A) Generally, as the carbon ratio increases up to a certain percentage, the properties of the alloy such as strength and hardness increase in direct proportion. B) Ductility and ability to absorb energy increase with the increase in carbon ratio. C) Steel, which is an iron carbon alloy, is the most used of all iron-based material. D) The alloying element that affects iron the most negatively is carbon. E) Pure iron has a low yield strength value such as 30 MPa.
