Notes
Elements not listed in the table may not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast. All appropriate precautions are to be taken to avoid addition of such elements from scrap and other materials used in production which would impair mechanical properties and the suitability of the steel.
*) Patented steel grade. |
