ASTM A105 Heat Treatment



2001

We need to know the best heat treatment for a machined part made from a bar of ASTM A 105 steel.

After the heat treatment the part will be cold shaped in two phases. We have thought about normalizing (A3 + 30 °C) and slow cooling over A1, but we are unsure if a normalization with lower quenching Temperature and Reheating A1. More over we do need a TTT for this material because our supplier does not have a particular diagram on that.

Many thanks in advance.

Hello Marino!

ASTM A 105 is for carbon steel forgings for piping applications- generally one would not have a bar of this material. The composition is 0.35 max C, 0.60-1.05 Mn, 0.035 max P, 0.040 max S, 0.10-0.35 Si, 0.40 max Cu, 0.40 max Ni, 0.30 max Cr, 0.12 max Mo, 0.05 max V, and 0.02 max Nb. Not very much alloy content, as you can see.

There is some information on heat treatment in the specification, in Section 5 and in the Supplementary Requirements. It does note that annealing is done between 1550 and 1700 F, with a furnace cool.

Good luck! lee gearhart
