Cast iron GJL300

Cast iron GJL300

Lamellar cast iron EN-GJL300

This cast iron alloy has excellent wear and heat treatment resistance compared with GJL200 and GJL250 alloys. Continuous casting and extrusion is also the common production method for the GJL300 to achieve a product that enjoys greater homogeneity and uniformity.

The above data are intended as a guideline since they can be found only on standard specimens cast automatically on in-ground molding equipment. The values actually found on a casting depend strongly on the thickness of the element under consideration and the morphology of the casting (in fact, these two aspects jointly determine the cooling curves and thus the set of mechanical characteristics).
