Print head nozzles

Hello! Can someone tell me which nozzles for the printhead are installed by the manufacturer by default in the printer package? Stainless steel or hardened? I received 2 sets of nozzles from Aliexpress 0.2 and 0.4mm… Outwardly, they are identical to those that were included in the printer kit. Also, in the settings of the printer itself, I found information that the nozzles are made of hardened steel.

In this regard, the question.. Is it possible to print with them using filaments containing abrasives? For example, carbon fiber?

…they say stainless 0.4mm.

You need hardened steel for CF etc. You can use softer nozzles if you want, but expect them to wear quickly (and become imprecise). Bear in mind that hardened steel nozzles are more damaging if they gouge the build plate, for example, and they have different heat transfer characteristics, so it’s not an automatic choice to fit hardened.
