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.
')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.
3)The stabilization may be made by use of titanium or niobium or Zirconium. According to the atomic number of these elements and the content of carbon and
nitrogen, the equivalence shall be the following:
