ferrous Alloys - Coggle Diagram
ferrous Alloys
low carbon steel
medium carbon steel
high carbon steel
stronger and harder than low carbon steel
a good mix of strength and toughness
machinable (lathe, pillar drill)
tough, ductile, maleuable
easily machined (cut)
rusts easily
nuts, bolts, car bodies
high carbon steel
strong durable tough harder than medium and low carbon steel
iron and steels :steam_locomotive:
iron and steels are classified according to the percentage of carbon in them
the more carbon in the alloy, the harder and more brittle it becomes
the most common ferrous alloys are cast iron and steel
iron
pig iron
it contains more than 4 percent carbon
pinkish, very brittle
made from iron ore in a blast furnace
cast iron
rusts easily
made from pig iron in a cupola furnace
hihg in compressive strength
easily cast into different shapes
steels
steel is a ferrous alloy of
iron
and
carbon
carbon percentage is less than 2.1 percent
steel is made by removing carbon from pig iron
stainless steel
low carbon steel plus chromium (stops it from corroding)
high resistance to corrosion
high speed steel (HSS)
high carbon steel plus tungsten and cobalt
hacksaw blade
