表1に、テスト済みのプレス硬化鋼合金の鋼組成を示す。
様々な温度と時間で鋼合金4340−2のサンプルをオーステナイト化したプレス硬化シミュレーションの後に、機械的特性は評価された。次に、サンプルを水冷された平らな銅製ダイで急冷した。室温および準静的速度での一軸引張試験を実施して、プレス硬化鋼の強度と伸びを測定した。表3は、指定された時間のオーステナイト化後のサンプルの処理温度と機械的特性をまとめたものである。試験サンプルは、現在のプレス硬化合金により可能になった低いオーステナイト化温度の利点を示した。表3に示すように、オーステナイト化温度が高いほど、降伏強度と引張強度が低くなった。加えて、最低のオーステナイト化温度で得られた極限引張強度は、プレス硬化前に1200秒間オーステナイト化した後でも1900MPaを超え、この合金のプロセスウィンドウに有益な堅牢性を示している。
プレス硬化鋼であって、鋼の総重量パーセントで:
0.0%〜6.0%、好ましくは0.0%〜2.0%、より好ましくは0.1%〜6.0%、より好ましくは0.1%〜2.0%、より好ましくは0.1%〜0.6%、および、より好ましくは0.4%〜0.5%のモリブデンをさらに有する、実施例4または以下の実施例のいずれか一つのプレス硬化鋼。
0%〜6.0%、好ましくは0.2%〜6.0%、より好ましくは2.0%〜6.0%、および、より好ましくは0.2%〜3.0%のクロムをさらに有する、実施例3および4のいずれか一つ、または以下の実施例のいずれか一つのプレス硬化鋼。
0.0%〜0.1%、好ましくは0.01%〜0.1%、より好ましくは0.001〜0.055%のニオブをさらに有する、実施例3〜5のいずれか一つ、または以下の実施例のいずれか一つのプレス硬化鋼。
0.0%〜0.15%、好ましくは0.01%〜0.15%のバナジウムをさらに有する、実施例3〜6のいずれか一つ、または以下の実施例のいずれか一つのプレス硬化鋼。
0%〜0.005%のホウ素をさらに含む、実施例3〜7のいずれか、または以下の実施例のいずれか一つのプレス硬化鋼。
実施例3〜8のいずれか、または以下の実施例のいずれか一つのプレス硬化鋼であって、Ms温度が365℃未満であるプレス硬化鋼。
実施例3〜9のいずれか、または以下の実施例のいずれか一つのプレス硬化鋼であって、オーステナイト化のためのPMTが850℃未満である、プレス硬化鋼。
実施例3〜10のいずれか一つ、または以下の実施例のいずれか一つのプレス硬化鋼であって、プレス硬化またはホットスタンピング後に、少なくとも1480MPaの極限引張強度および全伸びが少なくとも6%である、プレス硬化鋼。
実施例3〜11のいずれか一つのプレス硬化鋼であって、冷間圧延後およびホットスタンプ前に、アルミニウムベースのコーティングまたは亜鉛ベースのコーティング(亜鉛メッキ(galvanized)または亜鉛メッキ(galvannealed)でコーティングされた、プレス硬化鋼。
