    17-4PH H1150 vs 17-4PH HH1150 or double aged

    Hello All, Thank you all for your insight into my query. All the comments are very helpful in explaining the obvious to the untrained mind and gaining some knowledge along the way. May my next metals thread provide a little more comic relief and less, really? Enjoy the spring! MECOMAN

    17-4PH H1150 vs 17-4PH HH1150 or double aged

    Hello, We are looking for the difference between the two materials with regard to internal stress after machining, hardness properties and corrosion properties. We typically purchase the material in the H1150 and machine the part in the H1150 condition. We do the same with the H900 condition...

    super duplex ss

    Stonecold, Unfortunately the components are large, split in half and with many holes. The split at the joint has always been difficult to clad or coat, manufacture and provide a very smooth transition across the split-line. If clad after manufacture the split won't be of high quality (smooth)...

    Seal between PEEK and Duplex (other stainless), Titanium

    Hi FC2008, Long time since on the site, sorry about the delay. Exactly why, without my doing research makes my response less on the why and more on the what. The PEEK material is very stable under 300F. When thread profile cuts very well. The material is very resistant to creep, thus the...

    Seal between PEEK and Duplex (other stainless), Titanium

    Hi There, PEEK does thread very well. If wall is thick enough, you may try a pipe thread connection. Packing or a valve stem elastomer and compression device. Unsure on your diameters. Just some quick thoughts. Cheers, MECOMAN

    Hello, Curious what metal might be recommended for service in ferric chloride anhydrous at 180F? Any water produces nasty HCL as a by-product, thus material to be kept very dry. I was thinking Alloy 2205 may do well. However, need the material available in 16" pipe. Any ideas. Thanks in...
