Description
316Lタイプのオーステナイト鋼は、その化学組成が、重量パーセントで、0.03%未満の炭素、1%未満のシリコン、0.2%未満のマンガン、0.045%未満のリン、0.015%未満の硫黄、16.5%から18.5%のクロム、2%から2.5%のモリブデン、10%から13%のニッケル、0.011%未満の窒素、及び、鉄、及び不可避不純物であり、室温で、リダクションR=2.31で、静水圧押出しを受けた。上記鋼からなるビレット(1)は、直径がD1=38mm、長さが300mmのシリンダ形状であり、その一端は、抜き型(2)の角度に適合する頂角が2α=45°の円錐を有する。ビレット(1)を銅ベースのCS−90潤滑剤で覆った後に、ビレット(1)は、その円錐端が25mmの出口径の抜き型(2)の空洞部に挿入されるように、押出装置の高圧チャンバ(3)内に配置された。高圧チャンバ(3)は、ピストン(4)で閉じられ、周知の圧力伝達媒体(5)で満たされた。チャンバ(3)内の圧力の増加は、図1の矢印で示される方向へのピストン(4)の等速運動による。チャンバ(3)内の圧力が臨界値である970MPaに達すると、押出しプロセスが開始され、シングル押出しパスの間に、呼び径D2=25mmを有するロッドが得られた。これによって得られたロッドは、引張強度がUTS=1280MPa、降伏応力がYS=1100MPaであり、15%引き延ばされた。
実施例1に記載されたように、鋼が、室温で、リダクションR=2.56で、実施例1と同じ装置で、静水圧押出しを受けた。ビレット(1)は、直径がD1=40mm、長さが300mmのシリンダ形状であり、その一端が抜き型(2)の角度に適合する頂角が2α=90°の円錐を有する。ビレット(1)は、銅ベースのCS−90潤滑剤で覆われてから、ワンパス操作の間に、直径D2=25mmにまで静水圧的に押し出された。これによって得られたロッドは、引張強度がUTS=1310MPa、降伏応力がYS=1200MPaであり、14.5%引き延ばされた。
実施例1に記載されたように、鋼が、室温で、リダクションR=2.23で、実施例1及び2と同じ装置で、静水圧押出しを受けた。ビレット(1)は、直径がD1=37mm、長さが300mmのシリンダ形状であり、その一端が、頂角が2 24°及び抜き型(2)の形状に適合するα=90°の二重円錐を有する。ビレット(1)は、二硫化モリブデンベースのMolipas潤滑剤で覆われた後、ワンパス操作の間に、直径D2=25mmにまで静水圧的に押し出された。押し出されたロッドのオーステナイト鋼は、引張強度がUTS=1210MPa、降伏応力がYS=1140MPaであり、18%引き延ばされた。
