At What Temperature does Metal break easiest?

Question

At What Temperature does Metal break easiest?

Answer 1

Way below zero.

Answer 2

Well of course that depends on the type of metal as each metal has different melting points and boiling points and of course freezing points.

Since you are talking about a metal breaking, I would say in the very low minuses.

Answer 3

Break doesn't mean a thing in metalurgy.  Now , I'll expand that to mean at what temperature does a metal become brittle enough that it is no longer useable.

I have an alloy from a furnace that breaks at room temperature, it gets less brittle after it reaches 600 F.  I have a 316 stainless steel that is good to -325 F.  so there is a range for you.

Answer 4

Break is not really the proper term... you are probably asking at what temperature is metal brittle enough to fracture easily. Brittle fracture depends upon the pure metal and what other elements (carbon, oxygen, silicon, other metals) are alloyed with it. Carbon steel has a relatively high brittle fracture- about -20C. Stainless steel has a much lower brittle fracture temperature- depending upon the specific alloy, usually less than -300C.

From wikipedia

In brittle crystalline materials, fracture can occur by cleavage as the result of tensile stress acting normal to crystallographic planes with low bonding (cleavage planes). http://en.wikipedia.org/wiki/Brittle_fra...
