^*) max. addition (single element): 0,05%, total addition: 0,15%.
⁺⁾ max. addition (single element): 0,03%, total addition: 0,15%.
^**) the Fe content may be restricted to 0,80% for special applications.
^***) the castability is increased with increasing Si content, however high silicon content causes higher corrosion rates..
