Which range corresponds to 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 makes the steel very hard and wear resistant but less ductile and more difficult to weld. A carbon range around three-quarters of a percent up to about one and a half percent places the material in that very hard, high-carbon category. The other ranges correspond to progressively lower carbon contents, which align with lower hardness and strength and greater ductility and weldability. So the range 0.75-1.50% best fits very high carbon steel.
