Hardened steel nozzle 0.4 mm

A 0.4 mm hardened steel nozzle. Resists abrasive wear, so it suits the materials that chew through brass.

When you need hardened steel

• carbon- or glass-fibre filaments (PA-CF, PET-CF, PLA-CF);
• plastics with metal or mineral fillers;
• glow-in-the-dark and glitter filaments.

How it differs from brass

Hardened steel conducts heat worse than brass, so the print temperature is usually raised by about 5–10 °C for the same material. For plain PLA and PETG there’s no reason to pay more — brass is enough.

After changing the nozzle, recalibrate the Z offset.
