Ferroalloy grade indication method (GB7738-87):
(1) The combination of Chinese Pinyin letters, chemical element symbols and Arabic numerals indicates that the iron alloy product grade and mixed rare earth elements are represented by “REâ€.
(2) When using Chinese pinyin to indicate the product name, purpose, characteristics and process method, it is generally selected from the Chinese pinyin representing the Chinese character, and the first letter is taken in principle.

a, indicating the impurity element and its highest percentage or group
b, indicating the main element (or compound) and percentage
c. A ferroalloy product containing iron, represented by the chemical element symbol "Fe"
