    elements in appliances like toasters,
    silverware, pots and pans, and
    corrosion-resistant containers
A

alloy steel

17
Q

    in the universe
A

iron

22
Q
  • An alloy of iron that contains 2 to

    blast furnace.
A

cast iron

23
Q
  • A soft, ductile, fibrous variety that
    is produced from a semi fused mass
    of relatively pure iron globules
    partially surrounded by slag usually
    contains less than 0.1 percent
    carbon and 1 or 2 percent slag.
A

wrought iron
