鋼管的外徑和壁厚分別為323.9mm和20.0mm,。為評價(jià)圓周焊接部的特性,對整個(gè)焊接金屬部進(jìn)行了拉伸試驗(yàn),、維氏硬度試驗(yàn),、cvn試驗(yàn)和ctod試驗(yàn),。試驗(yàn)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(yàn)�,! —�(7)軸承行業(yè):目前滾動(dòng)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(shí)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(dòng)軸用精密管6000噸,,半軸套管1萬噸和各種輸油管等。
