Os elementos não especificados nesta tabela não devem ser adicionados intencionalmente, exceto para fins de acabamento do aço fundido.
Nota a) Não adicionar intencionalmente.
b) Mo da SNCM630 pode ter um limite inferior de 0,30%, dependendo do acordo entre as partes receptoras.
c) O Al de SACM645 é 0,70% a 1,20%.

Tolerância 3. Dimensions

Tabela 8-Tolerância das dimensões do fio laminado a quente

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

A tolerância das dimensões do fio com um diâmetro de mais de 50 mm depende do acordo entre as partes receptoras.
Nota a) O desvio refere-se à diferença entre o valor máximo e o valor mínimo do diâmetro na mesma seção transversal do fio.
