What is a Hardened Steel Nozzle?
Standard brass nozzles are soft—great for thermal conductivity, terrible for abrasive filaments. Print a few rolls of carbon fiber PLA through brass and you'll see the orifice widen, causing under-extrusion and poor print quality.
What is Hardened Steel Nozzle?
Hardened Steel Nozzle A 3D printer nozzle made from heat-treated steel alloys with high Rockwell hardness (typically 50-65 HRC) that resists abrasion from filled filaments containing carbon fiber, glass, metal particles, or glow-in-the-dark phosphorescent additives.
Hardened steel nozzles sacrifice about 50% of brass's thermal conductivity for 10x the wear resistance. This trade-off is essential for anyone regularly printing specialty filaments.

When Do You Need a Hardened Steel Nozzle?
Switch to hardened steel if you're printing any of these materials:
Highly Abrasive (Mandatory)
- • Carbon Fiber PLA/PETG/Nylon
- • Glass Fiber filled filaments
- • Metal-filled PLA (bronze, copper)
- • Ceramic-filled materials
Moderately Abrasive (Recommended)
- • Glow-in-the-dark filaments
- • Wood-filled PLA
- • Marble/stone PLA
- • Sparkle/glitter filaments
Best Glow-in-the-Dark Filament 2025
These luminous filaments require hardened nozzles for best results
Best Wood PLA Filament 2025
Wood-fill filaments wear brass nozzles faster than you'd expect
Frequently Asked Questions
Does hardened steel print slower than brass?
Hardened steel has about 50% lower thermal conductivity than brass, which can slightly reduce maximum volumetric flow. For most users, this means adding 5-10°C to your nozzle temperature. The difference is negligible for typical print speeds under 150mm/s.
Will hardened steel nozzles work with all filaments?
Yes, hardened steel nozzles work with all filaments including PLA, PETG, ABS, TPU, and specialty materials. They're especially recommended for abrasive filaments like carbon fiber, glow-in-the-dark, wood, and metal-filled materials.
How long does a hardened steel nozzle last?
A quality hardened steel nozzle can last 5-10 times longer than brass when printing abrasive materials. With regular PLA/PETG, they can last for years. The Slice Engineering Vanadium is rated for approximately 500+ hours of abrasive printing.
Do I need to change temperature settings with hardened steel?
Typically yes - increase nozzle temperature by 5-10°C to compensate for lower thermal conductivity. Some premium nozzles like the Bondtech CHT are designed to minimize this difference with special coatings and geometry.
Are ruby nozzles better than hardened steel?
Ruby nozzles offer even better wear resistance and thermal conductivity than hardened steel, but cost 3-5x more ($100+). For most users, hardened steel provides the best balance of durability and value. Ruby is overkill unless you print abrasive materials 8+ hours daily.
Conclusion: Which Hardened Steel Nozzle Should You Buy?
For most users printing abrasive filaments occasionally, the BIQU H2 at $8 offers incredible value. If you print carbon fiber, glow-in-the-dark, or wood filaments regularly, invest in the Slice Engineering Vanadium at $35—its durability and thermal performance justify the premium.
Voron builders should grab the Trianglelab ZS, while high-speed printing enthusiasts will appreciate the Bondtech CHT's exceptional flow characteristics.
