Chemistry composition of EN-GJS-450-10 cast iron

According to the standard DIN EN 1563, the foundries could adjust the chemical composition as long as the mechanical and physical properties of the castings could meet the requirements in Standards.

The following chart is an approximate chemical composition range for your reference.

C: 3.50-4.00, Si: 2.20-2.90, Mn: 0.3-0.6, P: 0.03-0.06, S: 0.02-0.040, Mg: 0.020-0.060.

DIN EN 1563 ISO C % Si % Mn % P % S % Mg %
EN-GJS-450-10 450-10 3.5-4 2.2-2.9 0.3-0.6 0.3-0.6 0.02-0.04 0.02-0.06

Foundry of EN-GJS-450-10 cast iron

Because of the comparatively high elongation, EN-GJS-450-10 ductile iron could be used for producing impact resistance casting parts. In addition, it has good low temperature impact resistance and good hardness. Thus it has been used for producing plough, plough pile, differential shell, plow point, valve body and high pressure cylinder.
