Looking for Temp/Pressure chart for liquid Argon

[sdumper]

I was going to try to blend Argon with r14 in a normal 3 compressor/ 3 stage cascade system.
Im having trouble finding a pressure temp chart for Argon can someone point me in the right direction?

I have already tried a blend or r1150 and Argon (just for a test) but im not certain the Argon is liquifying.
Condensing temp is -90c and pressure is relatively low 75psi/100psi. Im assuming im going to need much higher pressure or lower condensing temps but a chart would answer those questions rather quickly if some one can point me to one.

T critical = -122,45?C and P = 47,65barg

Thanks guys!!

A bit depressing but it is what it is I suppose...
