Four alloys, one tolerance standard
One tolerance standard across every family
Whatever the alloy, the finished part is held to the drawing. The weight range is the same end to end.
| Material | Designation | Typical castings |
|---|---|---|
| Mild Steel | IS 2062 | Side frames, brackets, housings |
| SG Iron | IS 1865 | Bolsters, axle box bodies, centre pivots |
| Cast Iron | IS 210 FG260 | Brake heads, general castings |
| Manganese Steel | IS 276 | CBC knuckles, wear liners |
Grade designations are the standard Indian specifications for these alloy families and are pending confirmation against the RDSO drawing set.
