Definition
Metals that contain iron.
Metals that will rust.
Magnetic.
E.g. Carbon Steel, Cast Iron, Stainless Steel and HSS. |

Definition
Two types: White cast and grey cast.
Brittle
Hard to weld
Good conductor
White: cannot be machined, machinery/ drain/manhole covers.
Grey: Easier to work with, intricate shapes, corrosion resistant, components/ disk brakes/ cookware/ braking systems. |

Definition
Alloy of Iron and Carbon.
Ductile, malleable and tough.
High tensile strength
Easily machined
Cannot be heat treated
Rusts
E.g. nuts and bolts/ girders/ car chassies. |

Term
| Medium (0.5%)/ High Carbon steel (1%) |
|
Definition
Harder than mild steel
less ductile and less malleable
can be heat treated
0.5% : garden tools/ springs
1% : hammers/ chisels/ drills |
