a The definition of deoxidation method is as follows: FN = Boiling steel is not allowed FF = fully-killed steel containing nitrogen-binding elements in an amount sufficient to bind possible nitrogen (E.g. 0.020% minimum total aluminum or 0.015% soluble aluminum) b It is allowed to exceed the specified value, as long as the N content increases by 0.001%, the maximum content of P decreases by 0.005% at the same time. The N content in the smelting analysis should not exceed 0.012%. c If the chemical composition shows a minimum total aluminum content of 0.020% and a minimum Al / N ratio of 2: 1, or if other sufficient nitrogen-binding elements are present, the above maximum nitrogen content limits do not apply. Nitrogen binding elements shall be noted in the inspection documents.
