Show answer
High-carbon steel is harder and more resistant to wear than mild steel, but is also more brittle (less malleable and ductile).
Also accept: It is harder and has greater wear resistance, but it is more brittle than mild steel.
Common mistakes: confusing mild steel as harder

Worked solution
High-carbon steel is harder and more resistant to wear than mild steel. However, it is also more brittle and is not as malleable or ductile.
