WHAT IS A FERROUS METAL?
Ferrous is used to indicate the presence of iron (FE). The word is derived from the Latin word ferrum ("iron"). Ferrous metals include steel, pig iron and alloys of iron including stainless steel. Ferrous metal is magnetic.
FERROUS METALS LIST
Wrought iron is made with less than 0.008% carbon. Because wrought-iron is nearly 100% pure iron it is very resistant to rust and oxidation. Wrought iron is strong, hard, fibrous and malleable which makes it is easy to weld plate and machine.
Mild steel is the most abundant of the ferrous metals. It contains between 0.15 and 0.30% carbon. Mild steel can only be case hardened; additionally it is pliable and it bends without great resistance.
Carbon steel, also known as tool or cast steel, is an iron alloy with 0.5 to 1.5% carbon. Carbon steel is hard and it can be tempered to make it harder. When tempered with proper heating and cooling, carbon steel forms a smooth skin of black oxide becoming extremely hard and brittle.
Cast iron is a frequently used ferrous metal. It is created by adding between 2 and 6% carbon to iron. Cast iron is extremely hard and strong which makes it very brittle. Cast iron is resistant to corrosion and compression.
Cast iron is generally classified as one of the following:
- Gray cast iron
- Malleable cast iron
- White cast iron
Stainless steel is an alloy that includes iron, nickel and chromium. Stainless steel has high resistance to corrosion and stains.
