[TheForge] steel idntification

[Sheldon Laing]

Hi all,

I have a few engine sleeves (the things that pistons run up and down
inside of to prevent wear on the engine block) and I was wondering if
anyone knows what kind of tool steel this is? I found a few of them in a
scrap pile in a railway yard. It look like each piston is about 1 litre
(I thinks that=92s about 60 cubic inches) and I found 4 of them, however =
I
think it is from a bigger motor than a 4 litre (300 cubic inches). Any
ideas on what kind of steel and any tempering advice?
Thanx in advance for you help.
