I wouldn't normally post something like this, but I know these people well and have worked with them for years.
The title is "Specification of Structural Stainless Steel: The Fundamentals".
There are recent (fairly) revisions to some Codes with regard to the use of SS in structural applications...
With a single post repeated over and over filling more than 30 pages there is something seriously wrong.

P.E. Metallurgy, consulting work welcomed
So I am working with somebody who is having some stainless steel (17-4PH) parts made by metal injection molding.
The supplier has now decided that there are some things that he can’t (doesn’t want to) do.
After tooling has been built and parts sampled.
I need some help in figuring out which...

When you look for these failures you see a lot of them.

I am looking for a laboratory in OK to do some MT0177-C testing.
The last time that I needed any of this done I could do it in-house.
So I don't have any experience with getting this done at outside labs.
I would prefer someone in OK, that you have used and would go back to, since that is where...
Is anyone out there familiar with working with this alloy?
This is one of those odd old MIL spec alloys.
Any advice?

I was doing some research for a customer, and came across this document from 7 years ago.
While I am working on adding updates I thought that this might be of use to some people so I will post it.
Thanks, Ed

Is your facility prepared for handling metals that may be radioactive...
I am sure that a number of us are there, I am.
Should we try to meet up at some point?
Let's see how many of us there are.

I am dealing with hot forged bar, about 6" OD.
It happens to be 15-5PH, but this should apply to any age hardened alloy.
Which position/orientation will have the lowest impact toughness?
I can think of nine different combination to take impact bars, but I only want to take two.
Which will give...
The punchline is that these are 20' long tubes.
They range in diameter from 1/2" to 4".
This is a 6% Mo stainless.
It is the IDs that we care about.
I have the facility and know how, but I don't have the permits.
I would prefer the upper mid-west (we are based near Milwaukee)but I am open...
Since I follow these closely I thought that I would make some comments.
Ni price right now are back to where they were at the first of the year. From a high of $24/lb Ni has dropped to $15/lb.
Even steeper has been the fall in SS scrap prices. I don't know what scrap sells for, but I know...
I know that they are used in drills and casing, but where is the specification? I need to know form dimensions for a 42mm rope thread. These are on some small diameter well casing prints that have no details.
Thanks

I have never worked in the bar side of the biz, always wire, castings or flat rolled.
Who makes large diameter SS bar???? I am looking for 4"-5".

We supply cold drawn 304 tubing. In the cold drawn condition the yield strength is roughly 110ksi (UTS 140ksi) and the hardness is about 30RC. The inside surface finish is 25microinches. Just for discussion let's say that the size is 1.000" od x 0.025" wall.
I have a customer that wants the...
I need to braze two stainless alloys together. Since one of them is a 400 series I really don't want to go over 1550F or it will go martensitic on me. But I need to have a material that will be able to take at least 1200F in service.
My first choice was a MetGlas Ni-Cr, but its temps are too...
