Very high temperature salts?

I was perusing Darryl Ellis' web site and I noticed that his high temperature salts are only rated to 1650F. That is too low for a lot of high alloy stainless steels as I understand the HT info I have been studying.

Is there a problem using salt pots for steels like S30V? I have gotten as far as having a cylinder (316L) welded up, and am trying to learn everything I can as I put together my first salt pot...and I just want to make sure that this will do everything I need before I go any farther. For now I am looking at treating steels from O1 to ATS34, but I would like to not limit myself in the future if (when) I try others...

Thanks in advance!
 
There are different salt mixtures for different temperature ranges. If Darren is dealing with Heat Bath salts then I believe he is offering Nu-Sal which is a pure sodium chloride salt that has a range which maxes out at 1650F. This is the easiest to deal with both from the standpoint of the user and for the seller in that there are no hazardous materials considerations and you can dispose of it as you like- it is only salt. To do stainless alloys there are salt mixtures that include other heavy metals such as bismuth and others and cover a higher range of temperature. They will be more involved to buy and ship and you will have to be more careful with them. Here is one that you will probably end up going to Houghton for, unless Darren has decided to take on the hassles of these other salts which he would not sell as much of as the Nu-Sal.
 
Kevin is spot on with his info (as usual!) :)

We do carry the low temp salts, which have to be shipped as hazardous material already. I've been tossing around the idea of getting in a high temp salt that would cover the SS range, but it won't be until later this Spring (probably around May).
