Cは、ゴス方位結晶粒の発生に有用な成分であり、かかる作用を有効に発揮させるためには0.001%以上を含有させるとよい。一方、C含有量が0.10%を超えると脱炭焼鈍によっても脱炭不良を起こす場合がある。したがって、C含有量は0.001〜0.10%の範囲が好ましい。
Siは、電気抵抗を高めて鉄損を低下させるとともに、鉄のBCC組織を安定化させて高温の熱処理を可能とするために有効な成分であり、Si含有量は1.0%以上とすることが好ましい。しかし、Si含有量が5.0%を超えると通常の冷間圧延が困難となる。したがって、Si含有量は1.0〜5.0%の範囲が好ましい。Si含有量は、2.0〜5.0%の範囲がより好ましい。
Mnは、鋼の熱間脆性の改善に有効に寄与するだけでなく、SやSeが混在している場合には、MnSやMnSe等の析出物を形成し結晶粒成長の抑制剤としての機能を発揮するので、Mnの含有量は0.01%以上とすることが好ましい。一方、Mn含有量が1.0%を超えるとMnSe等の析出物の粒径が粗大化してインヒビターとしての効果が失われる場合がある。したがって、Mn含有量は0.01〜1.0%の範囲が好ましい。
Alは、鋼中でAlNを形成して分散第二相としてインヒビターの作用をする有用成分であるのでsol.Alとして0.003%以上含有することが好ましい。一方、Al含有量がsol.Alとして0.050%を超えるとAlNが粗大に析出してインヒビターとしての作用が失われる場合がある。したがって、Al含有量はsol.Alとして0.003〜0.050%の範囲が好ましい。
NもAlと同様にAlNを形成するために有用な成分であるので、0.001%以上含有することが好ましい。一方、0.020%を超えてNを含有するとスラブ加熱時にふくれ等を生じる場合がある。したがって、N含有量は0.001〜0.020%の範囲が好ましい。
S、Seは、MnやCuと結合してMnSe、MnS、Cu2−xSe、Cu2−xSを形成し鋼中の分散第二相としてインヒビターの作用を発揮する有用成分である。有用な添加効果を得るためには、これらS、Seの合計の含有量を0.001%以上とすることが好ましい。一方、S、Seの合計の含有量が0.05%を超える場合はスラブ加熱時の固溶が不完全となるだけでなく、製品表面の欠陥の原因ともなる場合がある。したがって、S、Seの含有量は、SまたはSeの1種を含有する場合、SとSeの2種を含有する場合のいずれも合計で0.001〜0.05%の範囲が好ましい。
