There are some axes out there that I don't think you could chip no matter what you did to them.
http://www.enggjournals.com/ijet/docs/IJET14-06-05-230.pdfFrom what I gather, there was a lot more than temperature working against the Titanic.
Are you suggesting that if the water had been a little warmer, the ship would not have sunk - after hitting an iceburg?
If it didn't actually hit an iceburg, then the engineers and shipbuilders had/have a lot of 'splainin' to do! They didn't know that the steel, rivets etc. weren't up to it? Would they have fared better in the Mediterranean? Where were the inspectors?
Again, I would like to see some data on how 20 - 50 degrees F changes the strength/elasticity of steel, and what difference it makes in the real world - particularly with axes and frozen logs. I have chopped a lot of holes through the ice on lakes and rivers (sometimes a couple of feet thick) and never had a problem. I assure you that any attempts to warm those axes first would have been utterly useless after the first swing!
The effect of temperature is well documented on steel.
Does the Titanic ring any bells?
Good point. A lot of cheap home owner axes are so soft they'd just roll an edge and never chip.
Cold water, not freezing, is enough to cause a hull failure.
"A massive crack in the bulk carrier Lake Carling occurred because the grade-A steel in the vessel's side shell was susceptible to brittle fracture in cold water, the TSB said in its report on the accident.
A minor crack in the hull of Lake Carling as it was crossing the Gulf of St. Lawrence on March 19, 2002, became a 21.5-foot-long hull fracture because of brittleness in the steel exposed to temperatures near 32°, according to the TSB report. "

Well, for my money I'll take the experience and (most importantly) documentation of S_p's trail work and temps over the peanut gallery's internet knowledge and arts and crafts.
Sheesh.
So you're accusing S_p of making up the temps he was working in? Ok. 87 posts, and about half of them are arguments. Mmmmm...on the ignore list you go, troll.

Those Finns seem to be my kind of people!
His scanned book page a little way down has some Finnish text on it that was interesting:

"The axe is not to be thrown in the workplace. Nor is it to be used as a wedge or wedge shot. If temperature is below freezing the blade is heated up before starting work, either by rubbing or the glow of the fire, not the fire itself, or it will break. A broken arm (varsi - handle) is immediately replaced. When the axe is not used, it must be kept in a warm room well greased"
While the bit of an axe is subject to stress from use that is different, or perhaps magnified and subject to be affected more by less, this paper leads me and experience lead me to believe that you have to be pushing 0°f to have the steel of an axe bit be affected in a major way.Does ice get colder than 32F/0C? If it does, is it harder then?
What about green wood? There is a lot of water in there.
I don't know the answers to the above questions, maybe someone out there does.
It might help us understand what chopping in cold temperatures does to the axe.
