Stainless Steel Yeild Strength
Stainless Steel Yeild Strength
(OP)
I am looking for a non magnetic Stainless steel with a yeild strength greater than 800Mpa and a modulus of elasticity of around 200,000. Cost is a factor so I am looking for the most cost effective option. Any suggestions?

You specified a yield strength of 800 MPa which is equivalent to 116 ksi. This value exceeds the tensile strength for this alloy in the annealed condition. It can be cold worked to raise the tensile strength, but it becomes magnetic as it is cold worked. The values you specified will be very difficult to achieve for a non-magnetic stainless steel. Good luck.

28.6 million psi not ksi.
dbrando,
You need to look for another material - not stainless.

The modulus of elasticity I can't help you with (and no one else here can either).

It is your best bet.

What will this material be used for?
You said ease of machining is a concern, as is raw material cost. But the total cost of raw material, processing, machining, etc is what matters. For example, you might be better off starting with a forged blank of a more expensive material that reduces machining costs, but also provides better mechanical properties. EdStainless' suggestion of Nitronic 40 is good, but Nitronic 40 is only available in a limited size of bar stocks.
A better description of your application would be very helpful.

The application is a shaft within a high voltage relay. One end of the shaft is press fit into a AISI 12L14 low carbon steel, the other is attached to silver plated copper. The largest diameter of the shaft is 3.353 mm. The issue we are having is with attaching the end to the copper. The attachment method involves compressing a prong feature machined into the shaft. The prongs compress, are inserted into the copper, and then return to their original position. The material we are currently using, 303 Stainless, is yeilding when compressed.

With modest cold work (20% reduction) we hit 150ksi UTS/130ksi yield/24% elong in Nitronic 40.
