Anyone fabricating with Hardox?

I’m looking to try and make a corn mill grinding plate as my original one has broken in 2.
I have found a company that will supply a plate of Hardox 500 and all it will need is the small holes and grooves putting in it!
I don’t know anything about Hardox 500 so if anyone could answer a few questions it would be a great help?
Would I be able to grind grooves like the original in Hardox 500?
Is there a more suitable metal that would be okay to use to grind wheat?
What would the best metal be to use?
Thanks

As with all my projects at the moment, time slipped by and I didn’t get chance to do anything about upgrading the spinner deck or getting new vanes made up in Hardox or something similar. So the mild steel experimental vanes, that I made up last year, have done my entire season! 😳 They had a little tweak in position to improve pattern, and I rebuilt the current motors, and altered the size of them as a bit of an experiment too, which worked out ok. That might actually be progress.......

I suppose one thing it has proved, is that I could probably knock up some mild steel vanes every year or two and they would be fine for what I do. But I hope to investigate some tougher alternatives at some point. And might have a go with some stainless, which would be better in some ways.
On my old transpead they supplied a plastic wear strip that was bolted to the vanes and did about 15 years on fertiliser

Yes you can grind it but it will be a big job and you may burn your grinder out.
500 can be milled but i'm not sure how you will get that pattern.
Yes you can heat up 500 to bend or drill it but it will make it softer maybe to 400 were it has been cherry red.
Because of the higher carbon and ally content it will however last perhaps as well as 450.

Would Hardox 400 be much easier to grind than 500?

Diameter is 295mm, 12mm thick with a 102mm hole and it has a chamfered edge towards the hole, all measurements are approximate as it's an old steel casting

The only real way of doing that would be to cnc mill it. Carbide cutter will be ok with hardox 500. It’s the cost of having it drawn up then the time milling it. At least you’ll have the drawing for future productions.

The idea was to get someone to supply and cut the disk and I was going to grind the grooves in it, preferably in Hardox 400!
I've found someone who can supply a disk in 500 but as yet no-one in 400.

Send me sizes, we can laser cut 450 hardox in 12mm and send it out to you.
