  1. Elements not listed in this table shall 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 products to be machined a controlled sulphur content of 0.015% to 0.030% is permitted by agreement provided the resistance to corrosion is still satisfied for the intended purpose.

Option3:A sulphur content of 0.015% to 0.030% is specified.

  1. Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 0.50%
  2. Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 1.00%
  3. Where for special reasons,e.g. hot workability it is necessary to minimize the deltaferrite content,or with the aim of low permeability,the maximum nickel content may be increased by 1.50%
