Stainless Tool Steel
Stainless Tool Steel
(OP)
I have an application that requires the wear resistance of a tool steel, but also needs the corrosion resistance of stainless steel. I have been able to find suitable materials, but they are all powdered metal. The shape and size of the parts don't lend themselves well to molding and sintering, which means I will pay a premium for powdered metal bar stock and then machine a bunch of it away.
I understand that using powdered metal keeps the carbides evenly dispersed. My question is why are there so many mild steel wrought tool steels available, but when you switch to stainless the only thing available is powdered metal?

RE: Stainless Tool Steel
There are lots of lower alloy tool steels available, because cheaper is better (why use all that expensive chrome if you don't need it?). And for most stainless steel applications, the brittle nature of the 440 series can be detrimental (it makes a lovely knife, up until you chip the blade).

Right. Unless you want 440B or 440A. Or 440F.

We have used 440C and gotten pretty good results, but thought something with even more carbides would last even longer. We also have used D2 in other applications and it is very good, but this is a particularly corrosive environment. We might give it a try, though, and see what happens.
I also want to follow up in more detail on the other suggestions. I took just a quick look and they look promising.
Thanks for all your help.

We have used 440C hardened to Rockwell C of 54-58. This gives a pretty good balance between hardness and toughness. The 440C gives us pretty good results, but we are always looking for something better.
Thanks in advance for any suggestions.

RE: Stainless Tool Steel
To quote Crucible:
"The process lends itself not only to the production of superior quality tool steels, but to the production of higher alloyed grades which cannot be produced by conventional steelmaking."
