Analysis on 07MnNiCrMoVDR Steel Mechanical Properties

07MnNiCrMoVDR steel is used in high intensity and low temperature low-alloy that is quenching and tempering.Now that is widely used in vessels、steel pipe and so on.The paper analyzed the Weldability of Steel 07MnNiCrMoVDR,formulation of Butt-weld technology for Steel Plates,and Butt-weld Steel Plates for thickness of 38mm meanwhile adopted the quality controlling measures in process of weld.Then the Welded Joint was used in mechanical properties test,got the mechanical property parameters and the conclusion for that is to determine whether it will satisfy user's demands.
