    Corten vs. XTen-50

    Thanks all for the info. Corrosionman, I am unsure of the quantity of material they use but I know they do use Corten and often use Xten-50 interchangeably. Claiming that these materials are interchangeable is where the issue lies as a corrosion comparison is not something that they have been...

    Corten vs. XTen-50

    From what I understand, Xten-50 is the generic grade of Corten which many companies are using due to the lead time/cost of Corten. So, unfortunately Corten is not always an option. Although not exact, they have very similar properties but I have been unable to find a corrosion comparison which...

    Bolting

    Doesn't a bolt head fail due to the stress concentration at the transition from the shank to the head? If this is the case, then isn't it logical that a CS bolt would hold more load as the stress concentration factor is directly related to the radius of the transition. Smaller the radius =...

    Alloy 706 vs. Demin. Water

    Can anyone help me with the performance or longevity of Alloy 706 (90Cu/10Ni) tubing running no more than 190deg. demineralized water?

    Welding 316SS tubing to Medium P ENi Plated C22 fitting

    Thanks Ed, Ni plating is for protection against demineralized water @ no more than 190F and 80psi. The weld must meet these requirements as well. Autogenous via orbital is what we are currently looking at but I believe degredation of the Ni plating on the interior of the joint is going to be...

    Welding 316SS tubing to Medium P ENi Plated C22 fitting

    I am looking at an application where a medium phosphorus electroless nickel plated C22 fitting will be welded to a 316SS tube. I have joined these metals using GTAW with visual success but am concerned with what is going on at the microstructure of the weld. Does anyone know of any concerns...
