Cold work tool steel should have_________________?
Correct answer: B. High wear resistance
- A. High toughness
- B. High wear resistance
- C. Poor hardenability
- D. All A., B. & C.
Explanation
Cold-work tool steels must resist abrasion and deformation during cutting or forming, so high wear resistance is essential. Poor hardenability is not desirable, and although toughness matters, wear resistance is the defining choice here.
