A514 substitution options
A514 substitution options
(OP)
I work on the Weld Engineering side of our company. It has been proposed to use AISI 8625 cast quench and tempered as a substitution for A514 GH for spring hanger brackets. The reasoning is that the 8625 can be cast to near net, whereas the A514 must be fully machined. Is there a better option for this substitution? Preheat will occur, PWHT is unlikely. Part dimensions are, very roughly, 5"x5"x1.5". Thoughts?

What has been the performance of the A 514 bracket material? For material substitutions you need to carefully review material properties and this includes fatigue properties (if applicable) in addition to cost before making any off the cuff material substitutions.

So how is the current blank made? Forged? machined from plate?
If you change method you may also need to change properties in order to keep the same safety factors.
My first though is if you are not able to PWHT this it should be a steel with low hardenability.
Have you looked at microalloyed steels? I know of many with 90ksi min Yield, and some are stronger.
The material is not very expensive and the heat treatment is simple.

4130 as suggested by others is a good substitute either in the cast or forged form.
