- relatively heavy
3
Q
Advantages of Medium Carbon Steel
A
- tougher & harder than mild steel
4
Q
Disadvantages of Medium Carbon Steel
A
- less ductile/more brittle than mild steel
- better corrosion resistance than mild steel BUT still likely to rust
5
Q
Advantages of High Carbon Steels
A
- quite expensive
- very tough
- very hard
