GRX-810

I just read this article and thought, "hey, maybe that stuff could be used for a new mule? Or would it only work for handles?"

Interesting read. Don’t know the answer to the question. But it got me wondering can you 3D print a quality knife?

Would be cool if this material could be 3d printed into a knife. Don’t know anything about the subject but that caught my attention when it said this material could be used in 3d printing.

This just seems like sintering?

GRX-810 is in the wrong family of superalloys for use as blade material, and it has no carbides. It would also not make a particularly good handle material. It's about 10% denser than steel, and probably has a HRC somewhere around 40 so would scratch easily.

High tungsten stellites like Stellite 20 (45-50% carbide volume, ~60HRC, very high strength and extreme corrosion resistance) are more in the direction of what should be tried as a blade material. Stellite 20 powder can be HIPed into finished parts, and the PM/HIP parts have about 3x the toughness of cast Stellite 20 (but still only about 1/3 the toughness of Maxamet IIRC). Stellite 6 has seen some use as a blade material, but is much softer and has a much lower carbide volume than Stellite 20.

Stellite 20 is the end of the road as far as wear/abrasion resistant alloys go. To achieve higher wear resistance, you have to go to cemented carbide ceramics.

After a bit of google-fu it’s probably best used in a washer for the owner that sits on the couch and spydie-flicks he’s blade opened and closed a thousand times a minute. Will be able to withstand the heat generated



But basically a part in a turbine engine that gets extremely hot
