What is the carbon content range for very high carbon steel?

• A. 0.75-1.50%
• B. 0.45-0.75%
• C. 0.30-0.45%
• D. 0.05-0.30%

Answer: (A)

Very high carbon steel is defined by its high carbon content, which gives exceptional hardness and wear resistance while reducing ductility and weldability. In practice, steels in this category typically contain about 0.75% to around 1.5% carbon. This range captures the transition from high carbon toward the very high carbon end, where hardness is maximized and weldability becomes more challenging. The other ranges correspond to lower carbon levels (0.45-0.75% is high carbon but not as hard or wear-resistant as the very high category; 0.30-0.45% is medium-to-high carbon; 0.05-0.30% is low carbon). So the 0.75-1.50% range best represents very high carbon steel.
