Stainless steel extrusion nozzle for 3D printer

Has anyone found a stainless steel print nozzle for printer? I have some carbon fiber PLA--and it supposedly tears apart the brass nozzle. I've contacted Stepcraft, and no options available.

? any option other than buying a ton or replacements (at $20 each) vs. simply not using the harder-to-use carbon fiber PLA?

Thanks!
