① For long products. the max. S content may be increased for improved machinablility ba 0,005 % by agreement if the steel is treated to modify the sulphide morphology and if the chemical comb shows min 0,0020 % Ca.
② The maximum value for nitrogen does not apply if the chemical comb shows a minimum total Al content of 0,020 % or, alternalively, minimum 0,015 % acid soluble Al or if s ufficient other N-binding elements are present. In this case, the N-binding elements shall be mentioned in the inspection document.
③ Cu contenl above 0,40 % can cause hot shortness during hot bing.
