32PCS Mk8 Nozzles 3D Printer Extruder Nozzles Hardened Steel, Stainless Steel, Brass High Temperature Pointed Wear Resistant Nozzle 0.4mm,Compatible with CR-10, Ender 3/ V2 Ender3 pro,Prusa i3

Havent used the steel nozzles, but the brass is working awesome! I test each new nozzle by pushing a cleaning rod through it so it was nice these came with them. Installed easily enough using the enclosed wrench and went right at an 18 hour print. Im impressed. Money (and not a lot of it) well spent.

These are pretty nice nozzles look forward to use some carbon fiber pla with the hardened steel ones.

Good set at a reasonable price.

Exactly what I needed.

Not sure how feel about these, you get a multitude of sizes of both steel and brass nozzles, ranging from .02 to .08 which is cool. The trouble with that is figuring out which is which as the packaging doesn’t have them labeled. The main gripe I have though, are the steel nozzles as they don’t retain heat well and seem to clog moments after replacement, this is evident in all sizes given with testing on all three of my Ender 3 pro machines. I do recommend these however, to anyone curious about how each metal and size nozzle performs.

This was a really nice kit of assorted nozzles. I thought it was an assortment of brass and steel but it was various sizes as well which allowed me to discover a whole new world of printing. I love a .6 nozzle and would have never have intentionally tried/ordered a .6 nozzle. Not sure what other products this seller has to offer but I am very satisfied with this purchase. Happy Printing.

Ive used several of the sizes and styles with no clogs yet.

I tested the hardness of the steel nozzles using a indentron hardness tester. The actual values were half of the advertised value for HRC. Do not use if you actually need a hardened nozzle. Values of HRC were between 24.9 - 27.7

These do the job well on my 3D printer. They all appear to be good quality. Ive used several of the sizes and styles with no clogs yet.

Really on use the brass ones. Plenty of .4 in this package. SO far so good. Extremely happy and pleased with customer service.
