Is McMaster-Carr 11 second oil fast enough to quench 1080/1084? If so, how much will I need? I was planning on purchasing 5 gallons and using 2.5-3 at a time. I just want to make sure this will work before I drop the money on it.

Thanks Don! After reading all of the threads I can on quenching for the last few weeks, I decided to definitely go with a commecrial quenchant. If McMaster-Carr will work, it would be nice to save the money over the Parks. I've got my first knife just about ready to heat treat. Its 1/8" 1080. I also bought some 1084 from Aldo Bruno that I haven't worked with yet. I'll post some pictures later as long as I'm not too embarassed by the results.
 
11 second oil may work, but I believe a faster oil would work better. I think your choice would depend on the level of quality you want in your work. If I wanted the best for the 1084, I think I would go with the Parks #50. Have you checked prices with Patrick on this forum? Parks #50 would also do 1095 if you ever wanted to try it.
 
I did see Patrick's prices. It less than 1/2 the price to get the McMaster-Carr oil. That's the reason I was wondering if 11 seconds was fast enough.
 
"11 second" "28 second" etc are measurements based on a standard size sphere dropped in to go from x temp to y temp. that's not how long it's going to take to cool your blade.

Parks 50 is, by that measure, an "8" or "9" second oil. Yes it's a bit faster than the McMaster "11 second" oil, but not a /huge/ amount. There tends to be a misconception that a lot of people have that "oh parks will cool your blade in less than a second, and the mcmaster carr 11 second oil will take 11 seconds to cool your blade" that's not correct.
 
I don't see any benefit to Parks over McMaster's offering for higher maganese 10xx steels, the 11 second oil is fast enough. With lower maganese steels like 1095 I would be interested to see what appreciable difference these is.
 
Justin and AcridSaint, thank you for the input and clarification. I've been taking in so much information over the last couple of months that my head is starting to spin! I am so glad I found this forum. I have really been impressed with the quality of people I've encountered here.
 
Hi, where can I Buy Parks #50 oil? for 1080 or 1095 steel? I would appreciate any info, I'm new, I don't know how to get a hold or Patrick for prices, or anyone for that matter. Thank you very much.
 
Not to butt in but I have my first blade almost ready and was told I need to send it to someone to HT it with salt ? I appreciate any help . Thanks Wild Bill

I'm not a HT expert. I just learned about salt pot HT last week when I went to visit another maker that HT'd my blades for me. It is a very neat process, but is not necessary for 1095 or any steel. 1095 can be HT'd in a kiln or forge, and quenched in oil. I'm sure much more experienced makers will chime in.

FWIIW, I can't seem to find Parks 50 either. I haven't found any locally, and can't find any on the web. Every time I search Parks 50 I just get a bunch of links to this forum. :)
 
I have the McMaster Carr oil, I think I have the 28 second oil. I use it for O1 and 1084 and consistently get 62+ rockwell out of quench.
I imagine the 11 second oil will work fine.
 
Like I said 4 years ago (old thread), The 11 second oil will work fine. :)

Get Park's 50 for shallow hardening steel, like 1095, W1, W2.
 
For reference: I'm using 52100 with McMaster 11 second oil on 1/8- 3/32 thick blades and get anywhere from 61-64 out of the quench.

I dunk the blades straight into the 5 gallon bucket while agitating back and forth in a slicing motion.
 
Holy necropost, Batman!

I agree with Stan. Maxim has several oils that are readily available, reasonably priced, and accessible in knifemaker quantities.

My personal experience is that I gained a little bit of hardness and got better martensite conversion when I switched from vet grade mineral oil to Maxim's 10 second oil. The Mcmaster 11 second oil will harden 1084 just fine, and I sure as heck am not going to contradict Don Hanson. On the other hand, there's no real risk to hardening 1084 in a faster oil like the Parks'. It's a little faster than the steel requires, but not so fast that you'd have trouble, IMO.
