')Elements not listed in this 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 the addition of such elements from scrap and other materials used in production which would impair mechanical properties and

the suitability of the steel.

2)For bars, rods. sections and the relevant semi-finished products, a maximum content of 0.030% S applies. For any product to be machined, a controlled sulphur

content of 0.015% to 0.030% is recommended and permitted.

*Patented steel grade.
