    Looking For Texaco Quenchtex or Shell Voluta Quench Oil

    I am having a difficult time finding sources or vendors who sale Texaco Quenchtex or Shell Voluta Quench oils. I have called Texaco corporate to get the usual automated phone run around. No luck with Shell either. I am simply looking for a vendor who has one of the two so I can get a quote...

    Material for Roll-In Furnace Cart

    I am in the process of installing a used, walk-in tempering furnace, and I need to design/build a new, roll-in cart for this furnace. The furnace will be operated at 800 F temperature, but it is rated for 1200 F. The current furnace cart is in rough shape, and it is not strong enough to handle...

    Localized Surface Hardening

    metman, thank you for your post. Copper plating is something I will need to learn more about. It sounds promising. I won't be able to retap the threads after Copper plating, because this thread has to be single pointed on a CNC. It has a taper (1-2 degrees) and multiple thread starts...

    Localized Surface Hardening

    Good question. The diameters range from 1.25" up to 4.25". The thread is pretty much as deep as it can be without major design changes. The threads are currently peened. Althought the advantange is minimal due to the fact that when the thread erodes away from the percussion, the compressive...

    Localized Surface Hardening

    I am in search of a surface hardening process that can be contained to specific areas of a part. I am designing a system that is being driven into the subsurface with a hydraulic powered percussion hammer. The design calls for a series of tubular rods that are threaded end to end with a...
