Spheroidal Graphite Iron Hardness Tester

The ductile iron hardness tester applies pressure to the surface of a ductile iron specimen using an indenter to create an indentation, measures the size of the indentation, and converts it into a hardness value. It is used to detect the ability of ductile iron materials to resist plastic deformation and to control the heat treatment quality of ductile iron parts in foundries and laboratories.
