    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

    Expanding ProE for developing BOM, Routing, costing, book keeping & quoting...aka ERP

    Hello World, What is the good word for using the ProE parts list for developing into an inventory, routing, shipping, costing and quoting system for a small manufacture of many custom assemblies using the same raw material and some standard assemblies sharing a few components? Is this something...

    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...

    Seal seminar

    Hello Rayhawk. Another place to look into is at Georgia Tech in Atlanta, Georgia. They have a one week class once or twice a year. It is also offered in the UK, but I do not recall the city. Crush the day and the enjoy the week! Best Regards, MECOMAN

    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)...

    super duplex ss

    Steve & Ed, The material spec is passed to us for what we need to use as a material for our gizmo that is attached to equipment in the process. Ed, I am not familiar with the materials you mentioned, but I will pass along to see if our different suppliers have heard of them. Hopefully we...

    super duplex ss

    Hi All, Looking for sources to supply AllOY 2507, 904L or similar specs. Trouble we are having is stock size. We need at least 3" thick plate, 4" would even be better. Approx plate OD is 24". We are only able to source 1.5" thick plate. Application has exposure to the following chemistry: 55%...

    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

    relaxing 5/16" thick sheet EPDM

    Thanks All, We do use sulfur cured. We have been reverse rolling and applying heat. Still trying to determine if it doesn't return to curling.It does return a little, need to store longer to find results. We find the length changes( shortens after heating), still testing to determine if...

    relaxing 5/16" thick sheet EPDM

    Hello, We machine EPDM (55 durometer) in sheet form. It arrives in 9-12 foot long x 3ft wide coiled bundle. Once received the material is uncoiled to relax. Once machined into strips 1/4x1x30" long+ lengths we store on shelves and wrap in coils and bag. We have found the coiling to be a bad...

    ferric chloride service

    Thanks for the feedback. The plan is to keep it dry to avoid the HCL and increased corrosion. Does anyone have experience with in a dry environment? If so, what metals performed the best? Need to be able to fabric with 16" pipe and weld the materiial. We are not familiar with the Dow...

    ferric chloride service

    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...

    IP56 Ingress Protection on a Non-Tapered Thread

    Hi, Some other options other than gooooop. It would be helpful to know: What type of straight thread? size? male or female? When doing bsp or metric, they use straight female BSPP (parallel)with a male BSPT (tapered)or parallel on both and one uses an o-ring/sealing washer. Looking at your...

    Do splicing o-ring's affect properties.

    A few thoughts, Two best materials are NBR (nitrile) or FKM Super glue is only rates for water. Nothing over 200F and then with hydrocarbons, don't count on it. Splicing requires human craftsmanship, if having to repeat, likely to fail occasionally. Could it be changed to a flat gasket with...

    internal form threads M8 in size

    Cory, I read that the strength is less with a formed thread. I cannot recall where I read it on my searching of the web. My mind thought that the material would be work hardened during the process. My sense on why we have been having problems with the M8 1.25 is that the % engagement is too...

    internal form threads M8 in size

    Thanks for the reply. Curious if anyone is familiar with form threads. This is where the hole is drilled a little larger and the threads are formed in the hole instead of cut in the hole? Pro/con? Cheers, MECOMAN
