まず、本発明の成分の限定理由について述べる。
CuはPとの複合添加により耐腐食性を向上する元素である。この作用を得るためには0.04%以上添加することが望ましい。但し、多量の添加は焼き入れ性を増加させ延性が低下するため、上限を0.4%とする。
[Mg%]≧([O%]/16×0.8)×24 ・・・(1)
[S%]≦([Mg%]/24−[O%]/16×0.8 +0.00012)×32 ・・・(2)[S%]≦0.0075/[Mn%] ・・・(3)
[Si%]+2.2×[Al%]≧0.35 ・・・(4)
−100 ≦−300(C%)+105(Si%)−95(Mn%)+233(Al%)・・・(5)
仕上圧延終了温度はフェライトの生成を妨げ、穴拡げ性を良好にするためAr3 変態点以上とする必要がある。しかしあまり高温にすると組織の粗大化による強度低減、延性の低下を招くため950℃以下とすることが望ましい。冷却速度は穴拡げ性に有害な炭化物形成を抑制し、高い穴拡げ比を得るためには20℃/s以上が必要である。捲取温度は300℃以上になるとマルテンサイトを生成できず、強度が低下し、所定の強度を確保できなくなるため300℃未満とし、十分な強度を確保し、これによる伸びの改善を十分に得るためには巻取り温度を200℃以下とすることが望ましい。
表1に示す成分の鋼を溶製し、常法に従い連続鋳造でスラブとした。符号A〜Zが本発明に従った成分の鋼で符号aの鋼はC添加量、bの鋼はMn添加量、cの鋼はO添加量、eの鋼はS添加量、fの鋼はMg添加量が本発明の範囲外である。また、bの鋼は式(3)と式(5)、cの鋼は式(1)と式(2)、eの鋼は式(2)と式(3)、fの鋼は式(1)が本発明の範囲外である。また、f、gの鋼は析出物個数が本発明の範囲外である。これらの鋼を加熱炉中で1200℃以上の温度で加熱し、熱間圧延にて板厚2.6〜3.2mmの熱延鋼板を得た。熱延条件については表2に示す。
表2のうち、A4、J2は冷却速度、B3、F3は空冷開始温度、E3、G3、Q4は巻取り温度がそれぞれ本発明の範囲外である。
このように、本発明により穴拡げ率、延性ともに優れた高強度熱延鋼板が得られる。
