What is it mated with?
What is it now?
What size and shape does it need to be?

One option maybe ASTM A128, Hadfield Manganese, or AR Plate.
Down side is that the base material is non-magnetic which could be an issue when used with food products.
The stuff work hardens like crazy.

Hi EdStainless,
Thank you for your response.
The wear plate is mated with another disc which is coupled with the drive from motor. The disc rotates at 1400 to 1500rpm. The rotation of the disc, thus also rotates the wear plate with it.
The Wear plate has thickness 10mm and is in rectangle size of 900mm x 350mm.
We are in initial phase of design and were planning to use D2 material. But D2 plates result in bending when heat treated which can create problems in further machining.
Most of the wearing takes place due to abrasion of the food particles.
Please suggest suitable material.

Hi DAVIDSTECKER,
Thank you for your suggestions.
We are looking into the mentioned materials.

D-2 sounds good. Try different heat- treat such as : air cool, double temper, sub zero cool after quench, different austenitize temperature.

Thank you blacksmith37 for your reply.
Maybe we will finalize D2 material for the wear plate.

D2 just about has the lowest distortion and highest wear resistance of any tool steel.
You just need to plan on flat grinding after hardening.
At that thickness you may be able to air quench (maybe forced air) which should distort less.
