1) Cast analysis.
2) Method of deoxidation: rimming steels not permitted.
3) For long products, the maximum S content may be increased for improved machinability by 0.005 % by agreement if the steel is treated to modify the sulfide morphology and if the chemical composition shows minimum 0.0020 % Ca.
4) The maximum value for N does not apply if the chemical composition shows a minimum total Al content of 0.020 %, or alternatively minimum 0.015 % soluble Al or if sufficient other N-binding elements are present. In this case, the N-binding elements shall be mentioned in the inspection document.
5) Cu content above 0.40 % can cause hot shortness during hot forming.
6) Fe is listed as a Base element for this material, but its % value is not listed in the specification. The value shown is a calculated one.
