Ferrous Metals

Question 1

What is a ferrous metal?

Answer 1

A metal containing iron

Question 2

properties of low carbon steel/ mild steel

Answer 2

-contain 0.05-0.25% carbon
-low cost and malleable
-used for nuts and bolts or forgings

Question 3

properties of medium carbon steel

Answer 3

-contain 0.25-0.6% of carbon
-low carbon content makes it harder and stiffer but less ductile/malleablr
-used for springs and garden tools (trowels and shears)

Question 4

properties of high carbon steel

Answer 4

-0.7-1.4%
- hard, less ductile, tough and malleable
-tools hammers chisels and screwdrivers
