Inconel 718 forging supplier and Waspaloy bolts

[cjaseng84]

Hi,

I have some large forgings I need manufactured in Inconel 718 (approximately DIA1000mm x 200mm with a bore of 700mm). Can anybody recommend a supplier that may be able to supply these. We are based in the UK but anticipate having to use a US supplier or somewhere in the Far East.

On the same project we also require some Waspaloy bolts about M36 x 270 long. Again if anybody can recommend a supplier I'd appreciate it.

Thanks

For studs, nuts and bolts I always default to TS Verbindungsteile (Germany) for this stuff. No non-sense, German quality, and good price-to-quality ratio. They list UNS N07001 on their site, so they should at least be familiar with it.

Does this all need to be to AMS specs?

Not AMS specs, but it will need to comply to ASME.

Can you tell us more about this massive forging from this exotic material ?

Perhaps a sketch or general description of the process ? ... Why must your device comply with ASME (Section VIII ?)

How did you decide on the use of Inconel 718 over other materials ?

The project is covered by an NDA so I can't discuss any of the details on an open Forum. The Design, calculations and analysis are all in the final phase now though, the material has been selected based on our results. We have already received quotes on the afore mentioned Forgings and fixings but these are not as competitive as we'd like/need them to be for our budget, which is why I'm wondering if anybody could recommend some alternative suppliers to try.

Some fancy new design using highly specialized 60-year-old alloys and you think that it is too expensive?
You are talking about alloys that have a raw ingredient cost of $15-25/lb before it melted the first time.
And then they get melted and refined twice.
And then made into a product.
Sounds like cost wasn't one of the design criteria.

Fasteners should be available from Standard Pressed Steel, Jenkinstown ,PA.

Go with the previous recommendations.
Also definitely do not go to alibaba.com

no vendor likes working with those materials. only vendors that will touch it will be very expensive. so there better be rational for using these materials.

 

[Guest102023]

Vendors who can master fabrication with difficult alloys may find it very profitable.

If you weld only carbon steel tanks you are competing with the entire world. If you can fabricate nickel and refractory alloys the field narrows considerably.

You could try looking at the API Composite List for entities with API Spec 20B / Std 20C certification and then following up their web links. For the fasteners, API Spec 20F - there are some in the UK.
