Description
特に別段の明記のない限り、本明細書では、すべての組成を重量%で記載する。
実施例1によれば、チュービングは、0.2%耐力が室温において少なくとも125ksi、伸び率が室温において少なくとも18%、衝撃強度が少なくとも50ft lbs、最大硬さがRc42であり、清浄なミクロ組織要件を満たすように製造できる。
実施例2によれば、チュービングは、0.2%耐力が室温において少なくとも140ksi、伸び率が室温において少なくとも18%、衝撃強度が少なくとも40ft lbs、最大硬さがRc42であり、清浄なミクロ組織要件を満たすように製造できる。
実施例3によれば、チュービングは、0.2%耐力が室温において少なくとも160ksi、伸び率が室温において少なくとも18%、衝撃強度が少なくとも40ft lbs、最大硬さがRc47であり、清浄なミクロ組織要件を満たすように製造できる。
直径が大きく、壁が厚く、仕上げ用機器として有用なパイプの製造方法の利用可能性を実証するために、VIM+VARヒートHW1420を610mm(24”)のインゴットとして鋳造し、1121℃(2050°F)で熱間加工して、470mm(18.5インチ)の穿孔したビレットにし、1038℃(1900°F)で押し出して、OD318mm(12.5インチ)×壁厚54mm(2.125インチ)のパイプにした。低温の押出温度が効果的に、室温冷間加工(変形)であったものの代用となることを期待して、1900°Fという低温の押出温度を選択した。続いて、押し出した状態のパイプを1038℃(1900°F)/1h/WQで焼きなまし、704℃(1300°F)/8h/FCから621℃(1150°F)/8h/ACで時効処理した。結果は表6に示されている。この結果は、目標要件を満たす衝撃強度の向上と清浄なミクロ組織を示している。押出温度については、約2050°F以下の温度で十分であり、約1850°F〜約2050°Fの温度が好ましいと考えられる。
