Consider the following statements regarding tensile test diagrams for ...
Carbon has the maximum influence on the mechanical properties of steel. Iron-carbon alloys containing up to 2 per cent carbon are called carbon steel while those having more than 2% are called cast steel. With increase in carbon the tensile strength of steel increases but the ductility falls.

Consider the following statements regarding tensile test diagrams for ...
Explanation:
Tensile test diagrams are used to characterize the mechanical properties of materials, including carbon steels. These diagrams provide information about the relationship between stress and strain, and can help determine the ultimate strength, elongation before fracture, and ductility of the material.
Statement 1: As the carbon content increases, the ultimate strength of steel decreases.
This statement is incorrect. In fact, as the carbon content increases in carbon steels, the ultimate strength also increases. This is because carbon is a strong and hardening element in steel. It forms carbides, which contribute to the strength and hardness of the steel. Therefore, higher carbon content generally results in higher ultimate strength.
Statement 2: As the carbon content increases, the elongation before fracture increases.
This statement is incorrect. As the carbon content increases in carbon steels, the elongation before fracture typically decreases. Carbon steels with higher carbon contents tend to be more brittle and have lower ductility, which means they are more prone to fracture without significant elongation.
Statement 3: As the carbon content increases, the ductility of the metal decreases.
This statement is correct. As mentioned earlier, carbon steels with higher carbon contents are generally more brittle and have lower ductility. Ductility refers to the ability of a material to deform plastically before fracturing. Higher carbon content reduces the ability of the steel to deform plastically, making it less ductile.
Statement 4: As the carbon content increases, the ultimate strength increases.
This statement is correct. As mentioned earlier, higher carbon content in carbon steels generally leads to higher ultimate strength. Carbon is a strong and hardening element in steel, and its presence contributes to the strength and hardness of the material.
Conclusion:
Based on the explanations above, the correct statements regarding tensile test diagrams for carbon steels with varying carbon contents are:
1. As the carbon content increases, the ductility of the metal decreases.
2. As the carbon content increases, the ultimate strength increases.
Therefore, the correct answer is option A: 3 and 4.
