Alloy 254

Alloy 254

(OP)
Does anyone know the composition of Alloy 254?
What percentage of Au vs Ag and fillers?

RE: Alloy 254

From www.suppliersonline.com, the following is a compositional range of Alloy 254 (stainless steel).

Carbon     0.02 max
Chromium   19.5 - 20.5
Copper     0.5 - 1
Iron       Balance
Manganese  1 max
Molybdenum 6 - 6.5
Nickel     17.5 - 18.5
Nitrogen   0.18 - 0.22
Phosphorus 0.03 max
Silicon    0.8 max
Sulphur    0.01 max

These are the governing standards: ASTM A182 (F44), ASTM A240, ASTM A249, ASTM A269, ASTM A312, ASTM A469, ASTM A813, ASTM A814, and UNS S31254.

The standards may give you more information on fillers and/or tramp elements.  However, you may have more luck contacting a supplier/manufacturer directly concerning the elements you are asking for.  Typically, that information is in their hands.

RE: Alloy 254

I think that you have a different alloy in mind.  Can you give us a clue as to the composition and applications?

I'm sure it's not the stainless steel alloy I was looking for- but thanks!

 The application is for making a commutor ring per ASTM B-477.

RE: Alloy 254

(OP)
I found the composition- thanks for your help though.

In case anyone wants to know:

Alloy 254 (Gold alloy)10K- yellow

Au 40.67 -42.67
Ag 2.15 -3.15
Cu 43.83 -47.83
Zn 8.30 -10.30
Cd .25 -.85
