A recent research study published in the IntechOpen publication has suggested that ARNCO series hardbandings developed by US-based Arnco Technology are the best hardbanding materials currently available. The authors emphasized that the latest products ARNCO 350XT and 150XT can guarantee 100% no crack. The paper titled ‘Research Progress of the Drill String Hardbanding Materials’ reviewed the research history and status quo of hardbanding materials on tool joints.
