Source for hardened and ground 420SST?
Source for hardened and ground 420SST?
(OP)
I have an application which requires a small wear plate. In a previous design the entire part was made of 420 SST hardened to 50-54Rc and showed excellent durability, however the part has small complex features which are difficult ($$$) to machine in 420SST. A possibly better solution is to make the part from aluminum and attach a 420 SST wear plate. I would like to stay with 420 because of the proven durability. I am looking for pre-hardened and ground 420SST plate, .045-.055" which I can send to a shop to laser cut or possibly a vendor that can supply the part complete. An internet search for hardened and ground 420SST hasn't turned up anything promising. Anyone have a source for this kind of application. The parts are small and quantities are low so a 12"x12" plate will go along way.

You could also send me a dxf file of the part and I can make a better suggestion.

We can forget about trying other materials, I didn't mean to detract from the original problem.

Sandvik makes a modified 420ss called 7C27Mo2 (Hrc54) I dont know if they have it .040+ thick though.
