i would be bending 3/8 x 6" hot roll plate. The
stock i have on hand is 1144 and 4140. Any
ideas on thee best choice of material for this
project?

1144 stresspreoff is a delight to machine. Use it if you don't need
exceptional poperties, like long die life.

4140 can be more durable if properly heat treated.
