41CrAlMo7-10
Nitriding ability is good.
Structural parts with high surface hardness like piston rods, extruders, cylinders, shafts, straightening tools, measuring tools, etc.
1.8550
34CrAlNi7-10
Its nitriding ability and polishability are excellent.
It is used in screw and sleeve parts of plastic injection machines, injection shafts, gears and machine parts.
DIN 1.8550 (34 CrAlNi7)
Thanks to the aluminum it contains, its nitration ability
(nitrogen absorption) is high. It is a pre-hardened material
with a surface hardness of 66-68 HRc thanks to the aluminum
nitride layer, and its delivery hardness varies between 27-33 HRc.
