A friend just had his oil boiler cleaned and the service man replaced the flu pipe from the furnace to the chimney because it was soft.

Acid from the flue gasses will eventually erode the metal. How long that takes depends upon the particulars of the system.
As the metal gets thinner, it's no longer as strong as it was, and a lot of folks will call it "soft."
As to what it is... I've found flue pipes where I was literally able to poke my finger right through the side of the pipe. Others that were still hole-free, but soft as tinfoil.
Stainless pipe lasts longer under adverse conditions, but is quite expensive...
