ferrous
metals containing mostly iron and carbon
magnetic and will rust/ corrode
strong, rigid and hard
low carbon steel
ductile, high tensile strength, tough, malleable, poor resistance to corrosion
o.15-0.30% carbon content
melting temp: 1427C
used for nuts, bolts, washers, car bodies
medium carbon steel
harder than low carbon steel but less ductile, malleable and tough
0.30-0.70% carbon content
melting temp: 1425C
used for springs, gardening tools
cast iron
hard outer shell but brittle core, good under compression
3.5"% carbon content
melting temp: 1149C
used for disk brakes, machine parts, engine blocks, sheet furniture
