The chemical composition for O135 (Sweden: SS 140 01) gray cast iron:
The normal chemical composition for this grade is as the following:
C % |
Si % |
Mn % |
P % |
S % |
2.9-3.6 |
1.4-2.5 |
0.45-1.0 |
0.30 max |
0.12 max |
As for normal grey iron, the chemical composition is not important comparatively. The iron foundries could adjust the compositions according to their experience as long as they could meet the physical and mechanical requirements.
