IS 210 specifies requirements for grey iron castings used in engineering. It defines 6 grades (FG 150 to FG 400) based on minimum tensile strength, along with chemical composition guidelines, mechanical testing procedures, and quality acceptance criteria. Widely referenced in manufacturing, plumbing fittings, and infrastructure components.
Specification for grey iron castings including chemical composition, mechanical properties, testing methods, and quality requirements for castings used in engineering applications.
Key Values
FG 150 min tensile strength150 MPa
FG 200 min tensile strength200 MPa
FG 260 min tensile strength260 MPa
Practical Notes
! FG 200 and FG 260 are the most commonly specified grades for general engineering applications in India.
! Grey iron has excellent damping properties and machinability — preferred for machine tool beds and engine blocks.
! Always specify the grade clearly in procurement — FG 150 is significantly weaker than FG 300.
! For pressure-retaining castings (valves, pipe fittings), use IS 210 in conjunction with IS 1030 (carbon steel castings).
