Answer / m.venky

2% to 6.67% of carbon in iron is called as cast iron and
below 2% carbon called as steels.
Composition of Cast Iron:
Carbon - 2.5 to 3.7%
Silicon - 1.0 to 3.0%
Manganese - 0.5 to 1.0%
Phophorus - 0.1 to 0.9%
Sulphur - 0.07 to 0.10%

Answer / karthick

if the carbon content is more than 2 precent in an iron-
carbon alloy then it is termed as cast iron

Answer / chetan panchal

Cast iron is an alloys which contain more than 2 % Carbon. there are two types of cast iron. one is grey cast iron and other is spheroidal graphite iron of ductile iron which is treated with Magnesium with grey cast iron.

carbon: more than 2%
Si: 1.8-2.3%
Mn:0.5-0.8% max
P:max 0,01%
S:<0.02%
Cu: can be less than 1%

Answer / a.jothi

Carbon by weight varies from grade to grade.
JIS standard grades are
FC-15; FD-20, FC-25, Fc-30 FC-35
Iso Standard
Grade 15; 20; 25; 30 35; 40
Carbon: 1.5%; 2.0%; 2.5% 3.0% 3.5% Respectively;
Silicon 1- 3.0%
Manganese 0.2 - 1.0
Sulphur .02-0.25%
Phhosprous .02- 1.0%

Answer / paul

composition depends on grade.
grade 150 being soft and easy to machine. 300 being tougher
and harder to machine.
