Genuine E3D Hardened Steel Nozzle V6 (1.75mm) 0.40mm (V6-NOZZLE-HS-175-400)

I bought 2 for my 2 prusa mk3s. One clogged immediately, which could have been the glow in the dark pla and the nozzle being too hot. But the second one worked for about a week then made uneven extrusions that couldnt get passed a 3rd or 4the layer. I changed the nozzle back and everything is working fine. Pretty annoyed that both nozzles had issues. *Update I returned the problem nozzle a month ago to get a replacement and still have not received a refund or replacement. *Its been two months. The second nozzles bore is also not straight. Very displeased with the amount of headache this has caused me. I straight up want a refund for both nozzles. The return on the first nozzle has still not been processed

Quite a bit more than brass but well worth it. Lasts much longer and doesnt clog like the brass ones do.

Purchased Genuine E3D Hardened Steel nozzle for printing exotic materials. Nozzle is made of high quality hardened steel which lasts indefinitely longer than softer nozzels. Highly recommended for anyone printing exotic materials like carbon fiber composite filament!!!

I’ve run a fair amount of carbon fiber reinforced nylon through it and still puts out beautiful prints.

I installed this nozzle on my Ender 3. I immediately noticed it was under extruding while doing its first print. I tried to reinstall the nozzle just to make sure I didnt do it incorrectly the first time but the problem continued. I set my extrusion settings to 150% then to 200%. The prints started to stick better but the nozzle became clogged and stopped printing half way through the first layer. You have two options. It will either under extrude or get clogged.

This is not genuine, wanted to use on my printer with high temp materials and get constant clogs. The filament sticks to the surface.

I have a Creality CR-5 Pro H and this thing has been printing beautifully with high temp ASA

PETG just sticks and then ruins the print. I like to print things for the outdoors and I must use PETG so this does not work for me or PETG.

Being a machinist for 45 years I have the resources of a hardness tester where I work. I decided to test two of these nozzles for hardness. I had to flip them on there side in order to test a flat surface. I checked all sides of the hex. 60hrc or Rockwell was the result. By comparison a hand file would be around 60hrc or a good pocket knife. Not sure what kind of steel they use or the heat treating process they use. Hope this helps answer the hardness question.
