Why same casting has different hardness and machineability
properties? One spot it is found hard for machining and
another spot soft? It is FG 260 grade for Cast Iron.
Answer Posted / anil kamat
If it is a free flow single gate single runner casting then
the density variation leads to the diffrence in properties
across various sections. To get uniform density variation
usually pressure flow multigate multirunner castings are
preferred.
