CTS XHP stainless steel has been hard to source in the custom knife maker market so it isn’t well known. It is powder technology smelting so it is fine grained and clean.


Carpenter CTS-XHP is often compared to Crucibles S30V steel. The steel has slightly better edge retention and great corrosion resistance as compared to S30V. It does give up a bit of toughness to CPMS30V. This steel outperforms 440c in all three categories of edge retention, toughness and corrosion resistance. It’s going to make a great slicing and cutting steel on a fixed blade, folder or kitchen knife. It’s not going to be the best choice for a chopper. Check around the net on cutting tests and other performance tests. It has always done well and is a high performing steel we in the custom world should know more about. The issue has been Carpenters business model ignores the custom knife steel market. It’s too small for them to bother with. We worked with their only wholesale distributor and developed a distribution channel we can work with and we can now bring this steel to market. 

This steel likes to work at 60 to 61HRC

Bring to 1400/1500F and equalize (let it soak for 10 minutes)

Bring it up to 1850F/2000F (I prefer 1950F) for 30 minutes

Quench in air or plate quench.

Temper 400F to 600F twice at 2 hours each. Cool to room temperature in between tempers. Temper at 400F for 60.5HRC


There does not seem to be any data around cryo treatment but as typical with all these “super stainless steels” there is probably some benefit from cryo treatment between quench and tempering.
