- The lower limit of 'Si' does not apply in case the content of 'Al' in the steel is min 0.020%.
- With the prior agreement of the purchaser, the manganese content may be increased, provided that the sum of the carbon content plus 1/6 of the manganese content does not exceed 0.40%
- This grade is produced normalized or equivalent to normalized rolling
- Copper content shall be minimum 0.20 %, if copper-containing steel is specified in the purchase order.
