Cost difference between grade 304 and 17-4PH and HyTens
Cost difference between grade 304 and 17-4PH and HyTens
(OP)
Hello.
I am thinking of changing material of some components in a machine from steel 304 to 17-4.
And I’m wondering roughly in percent how much more the 17-4 steel costs.
If anybody knows the price ratio for 304 and HyTens I would also be happy.
Thanks Thomas.

But first, why 17-4PH? Do you need more strength and less corrosion resistance?

you keep me company. I thought that I was the only one who did not know Hy Tens.
However, now a google search indicates that it is a low alloy tool steel.

It will be for better wear resistance.
The price will be for Condition A.
Price for ageing I already have.
And is Condition A suitable for punching operations?
Thanks Thomas.

The for of the material is sheet.

I was thinking of condition H900 due too the high strength.
I am not so a native English speaker so the word punching may be wrong used. The process may be stamping. The thickness of the plate is 2.5mm.
Also does anybody know where to find data for 17-4 in -94F (-70C) the application is a ledger plate in a drive chain for a freezer.

As I recall you don't want to use the high strength condition at low temps.
You might also consider using 17-7PH. It will process in the "A" condition and can given the RH heat treatment to reach high strength.

Also here is a NASA link I use quite often:

Look for an article entitled, "Stress corrosion cracking evaluation of precipitation-hardening stainless steel".
It is very useful information.

We only weld tubing in 17-7, so I am not positive.

Use the NASA link from the above post
http://ntrs.nasa.gov/search.jsp?N=4294960486
and find the publication below;
Low Temperature Mechanical Properties of Various Alloys, NASA-SP-5921 this publication will contain low temperature properties of 17-4 and other metals.
