The hardened steel nozzle is ideal for high-temperature print with filament like carbon fibre. 

The hardened steel is more harder and more wear-resistant than brass material nozzles. The

nozzle applies to 1.75mm filament. The coating would reduce the filament sticking on your 

nozzle and bring more smooth printing exper.
