# Best Hardened Steel Nozzles for Abrasive Filaments (2026) Source: https://filamentprintlab.com/best/hardened-steel-nozzles Updated: 2026-10-20 Publisher: Filament Print Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://filamentprintlab.com/how-we-research#our-score Hardened steel nozzles resist the wear that abrasive filaments inflict on soft brass, so wear resistance is the whole point. Look at the steel grade and any coating, since some add a low-friction surface for smoother flow. Check thread compatibility with your hotend and confirm the size range you need. Note that steel conducts heat slightly less efficiently than brass, so you may need a small temperature bump to match flow rates you are used to. These nozzles suit anyone printing carbon fiber, glass-filled, wood, glow-in-the-dark, or metal-fill filaments, all of which chew through brass fast. They cost more but last far longer with abrasives. A practical tip: keep a hardened nozzle dedicated to abrasive filaments and a brass one for everyday PLA and PETG, since brass still gives slightly cleaner flow on non-abrasive materials, and matching the nozzle to the filament gets the best of both. ## Picks ### 1.
