Suggestions- suitable material for extrusion nozzle
(OP)
Good day Gentlemen,
I need some help selecting a grade of hot work steel or other variety that will survive in this environment.
Application- Nozzle for extruding abrasive plastics at high temperatures. Nozzle measures 3mm long X 1.5mm in diameter with a through hole starting at .75mm then stepping down to .25mm.
Requirements-
-maintain properties up to 450c
-good abrasion resistance
-fair machinability
-fair ductility, pre hardened (cold forming of tip may be required to reduce orifice size)
-corrosion resistant
-commonly available
Nozzle will not experience any physical abuse in service. Thanks in advance

The plastic contains glass or carbon fibers.

I have used SiC (sintered, not reaction bonded) and BC dies as well. Contact CoorsTek you may be surprised at how reasonable they are.
If you want to go metal I would look at Co based alloys such as Ultimet from Haynes, it has outstanding corrosion and wear resistance.
