I believe you may need to use oil instead of water - read up on it (and be very careful)...

As others have said, yep - that'd do it.
Aside from quenching in oil, you may also get some mileage from quenching in methylated spirits. Yes really!
Years ago as a jeweller, we'd quench in metho to make the metal as soft as butter. Since it's got such a poor heat capacity, it can't carry the heat away anywhere near as fast as water does, so it would make the metal even softer than if it was heated then allowed to air-cool. Depending on the size of the article, this may be a very dangerous proposition - we would always submerge the metal in enough liquid to well and truly cover it. I.e we'd use about 20 or 30 times the volume of the hot metal.
Red-hot copper/gold/silver wire/bar quenched in metho ended up considerably softer and more ductile than quenching in water.

I did...three acres worth. I then started tilling the garden.

Quite the opposite, in my book.

Yep. WHat you need to do it get it red hot, the dip it in water, then reheat it to blue, then dip it. That way you will make 'spring steel' and hopefully maintain a nice blue colour.

Not really relevant now that you have replaced the spring, but another aspect of dealing with forming spring steel is hydrogen embrittlement http://en.wikipedia.org/wiki/Hydrogen_embrittlement[^]. I have experienced this problem in aircraft production - took a lab analysis to discover the cause of the sudden fractures and a vendor change to solve it.

In welding class we had to peen our welds - hitting them while still red-hot with the rounded end of a ball-peen hammer. It was to relieve the stresses caused by the differential cooling the two pieces as they cooled at the very-localized, very-dramatic heat differential of the weld line. Something about carbon, crystals, and brittleness was mentioned too.
According to Wikipedia's article on peening, " in 1930, a few engineers at Buick noticed that "shot blasting" (as it was originally termed) made springs resistant to fatigue. " I always tend to peen my welds -habit more than necessity since everything I weld tends to be over-engineered.
Peening the new bend as it cooled should have made it "tougher", but YMMV.

Shot peening is normally used to put the surface layers into compression which improves fatigue life through fewer stress reversals.
Peening of welds is generally frowned upon due to inducing localized brittleness which may induce cracking.

Interesting - perhaps that's why we were taught to peen while our welds and surrounding metal were still red hot - relieves differential cooling induced stresses. Compare with the cold-metal shot-peening that induces surface compressive stresses.

There are a variety of quenching processes. In general the faster, the more hard and more brittle the metal. In really rare metals, this quenching starts in a 540 degree oven that you spend a couple of weeks getting it down to 150 degrees where you can then air cool it. I haven't looked at this since the 70's when I was studying to be a Mechanical Engineer.

She has a 'D' in that class.
Maybe I should stop buying her gum...

Ok, as none of you know I am building a web based business in my ample [lie, limited] free time. And it is so much fun, it just makes the innovation juice pour into the brain with ideas. For example, obviously, when I go live I need to get a web host. Web hosts with shared hosting are cheap, dedicated hosting is expensive, and home hosting is a labor of love. So remembering how Plenty of Fish scaled so well (CDN, CDN, CDN) it occurred to me to CDN my own site (not erlglobal). (Bonus, cdn is cheaper, nearly than hosting)
So I am going to host all of the images, scripts css on the CDN, and the products and other shared JSON files as well. Working in an enterprise environment I would have never cared before but having to actually pay and control costs forces me to look at just what I am doing! I was kind of worried because ASP.NET is a resource hog.
Really, this is just one of the many things which I am not going to itemize, just so much fun. If only I had customers! But wait, I can't go live until it is perfect ... just ... one ... more ... tweak : ). BTW, why can't CC providers (braintree) provide a simple API? Easy Post wins on the simple API front. First place that advertised simple, easy, api that I was actually able to get fully up and running in under an hour.

Have you looked at https://www.cloudflare.com[^] they offer free cdn + other services. I use them for most of my clients.

Compared to what? PHP on Apache?, node.js? I've run a site with hundreds of thousands of users a day on a pair of servers with dual 266Mhz processors and 256Megs of memory on ASP.Net 1.0 without issue.

I had to take a break from MMA to help my brother out. He was having some hard times, so I had his 2 kids for a bit. I already had my other brother living with me, and my wife lost her job, so that was too much scheduling and finances.
Now everyone is out of my house. I have set up a schedule for modest saving since I spent everything I had put away to help the family. We can't save a lot, but meh whatever. At least we are saving again. So, that puts me in a position to do MMA again, at least short term.
I've picked a NAGA tournament in St. Louis MO that I'm doing in June. I hope to schedule a fight this summer as well. I'm super stoked. I just started back at the gym Friday, and did some sparring. So I'll be training there for fitness, MMA, and BJJ except for Tuesday and Thursday. Those days I'll be hitting weights and then programming on side projects.
On top of that, I have the spartan race april 26th and I get to finally have my vacation on the appalachian trail may 2nd - 12th. This summer rocks!

I have found that being an in-shape programmer with a weight lifting hobby is bad for the career. No matter how much of a kitten you are people continuously go behind your back to your manager and claim to be intimidated. Just because I defenestrated one person, that one time. Sheesh, it was a one-story building!
Long story short, just because someone likes to fight out of work doesn't make them a threat. Physical fitness is a great zen.

In our small group of around 15 people, we are two martial artists, two EX-martial artist and two fitness freaks. That doesn't seem to be a problem for anybody else... 
But then again, neither of us have defenestrated anybody. We work on the fourth floor...
