Which metal is used to make alloy steel for armour plates, safes and helmets ?
- A \(\mathrm{Al}\)
- B \(\mathrm{Mn}\)
- C \(\mathrm{Cr}\)
- D \(\mathrm{Pb}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Mn}\)
Step-by-step Solution
Detailed explanation
Mn is used to make alloy steel for armour plates, safes and helmets as Mn increases harden-ability by lowering transformation points and causing transformation to be sluggish.
