Al content in low alloy steel forging
Al content in low alloy steel forging
(OP)
Quick scream for help.
I am looking at ordering billets of low alloy steel forgings, idealy I was looking for an aluminium content of between 0.15- 0.35%, I am curently being offered materials with contents below 0.1%
what i am looking at is what is the relationship of Al in steel and I am looking in the right direction?
My belief is that it aids the grain structre growth enabling hardnability of the metal, and also providing a degree of corrosion resistance to the material?
will a reduction to 0.1% Al have a drastic effect on the material?
thanks in advance to any help

I would suggest that you specify the alloy steel forging to a recognized international standard like ASTM.

This is what I curently have specified anyway, it is possible that it may need revising, but the values are stipulated in a componany material specification?

The aluminum in your specification could be added for grain refinement - however fine grained steel may not be what you want because the creep strength will be reduced. This material is used for elevated temperature service - so I see no reason for using aluminum as a deoxidizer or for grain refinement.
