ferrous metals

metals containing mostly iron and carbon

magnetic and will rust/ corrode

strong, rigid and hard

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

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

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
