S30V heat treatment

claude · Jul 9, 2003

I imagine this has been discused before but I just purchased 6' of the stuff and the supplier was suppose to sent the heat treat temps and procedure and never. Does anyone out there have the procedure and temperatures, I think that someone once told me that it needed to be nitrogen quenched, but i hope it is not necessary as I don't have the necessary equipment. Thanks.

Hey Claude,

S30V is a nice steel to work. It is very difficult to get a highly refective finish though.

Here is my last s30v HT: http://www.bladeforums.com/forums/showthread.php?s=&threadid=251958&highlight=s30v

Since you don't have liquid nitrogen, get some dry ice from your local welding supply outfit. Dry ice it for as long as the ice remains.

Hey there Kelly! Give Thomas a call, as he's been using this stuff the last little while, and I'm sure he's got a great process worked out. He can also hook you up with an outfit in Calgary the does deep cyrogenics for about $5 a blade, with a fairly quick turn around time. If you decide to go with dry ice, MediGas (on Blackfoot Tr.) is the only game in Calgary. Give me a call sometime!

I would call crucible and have them fax/email you their specs.

They have a few profiles that you can use for different Rockwells.
