G15 is a most basic material grade of gray cast iron in Italy standard UNI 5007. It is equal to EN-GJL-150 in European standard EN 1561.
The followings are the chemical composition, mechanical properties, typical applications and the other equivalent grades of UNI 5007 G15 gray cast iron.
Chemical Composition for UNI 5007 G15 Gray Cast Iron:
The normal chemical composition for this grade is as the following:
C |
