Gli elementi non specificati in questa tabella non devono essere aggiunti intenzionalmente se non allo scopo di finire l'acciaio fuso.
Nota a) Non aggiungere intenzionalmente.
b) Mo di SNCM630 può avere un limite inferiore dello 0,30%, a seconda dell'accordo tra le parti riceventi.
c) L'Al di SACM645 è compreso tra 0,70% e 1,20%.

3. Dimensioni tolleranza

Tabella 8-Tolleranza delle dimensioni del filo laminato a caldo

直径	直径公差	不圆度
<15	±0.3	<0.4
15<d≤25	±0.4	<0.5
25<d≤32	±0.5	<0.6
32<d≤50	±0.6	<0.7

La tolleranza delle dimensioni del filo con un diametro superiore a 50 mm dipende dall'accordo tra le parti riceventi.
Nota a) La deviazione si riferisce alla differenza tra il valore massimo e il valore minimo del diametro nella stessa sezione trasversale del filo.
