Ferric stainless steels compared to austenitic stainless steels________________?
Correct answer: D. All A., B. and C.
- A. Have lower corrosion resistance
- B. Are harder to fabricate
- C. Are less ductile and hence less suitable for cold pressing
- D. All A., B. and C.
Explanation
Ferritic stainless steels generally have lower corrosion resistance, lower ductility and poorer cold-forming ability than austenitic grades. These differences make them less easy to fabricate, so all three statements are accepted.
