9cr2mo圓鋼庫存充足
鋼管的外徑和壁厚分別為323.9mm和20.0mm。為評價圓周焊接部的特性,,對整個焊接金屬部進(jìn)行了拉伸試驗,、維氏硬度試驗,、cvn試驗和ctod試驗。試驗表明,,在haz中看成不到明顯的硬化,。將x90鋼管母材的應(yīng)力比r的變化范圍設(shè)置在-1~0.7,進(jìn)行高循環(huán)疲勞試驗,�,! —�(7)軸承行業(yè):目前滾動軸承座圈的生產(chǎn),以圓鋼為原料,,切片后經(jīng)沖壓制成。大軸承座圈還將實心棒料掏空來制作,,金屬利用率不到40%,,迫切需要-、軸承鋼厚壁管材,。(8)汽車工業(yè):95年傳動軸用精密管6000噸,,半軸套管1萬噸和各種輸油管等。
