Zeron 100 maximum deformation 2

[Hercules28]

Dear all,

I want to reduce Zeron100.

How much can I reduce it ?
I guess a 25% is normal but how do I calculate the maximum reduction?

I guess maximum reduction may be the max force your tools can apply but assuming I got beefy tools.. how much reduction until my material gives away?

Now what does give away mean? I guess depends on application. Let's say that at this point all I care is not cracking it and secondary salt spray corrosion at 100F temp.

Thanks,

Herc

Herc,

Do you mean tube reducing? Or thickness reducing by cold rolling?

 

[Hercules28]

Tube reducing by spin forming.
You think I can extract a tensile bar from a SCH 40 SS?

Schedule 40 of what tube size??????

If the work is compressive then 50% reduction should not be a problem.
If there is tensile deformation involved then 20% may be the limit.
You will want to re-anneal before you put this into service.

Meteng, size is 2-4 in.

Cold working limitations will be equipment driven before you reach the forming strain limit. The issue will be re-solution annealing to remove cold work and restore corrosion resistance.

A short anneal time will work, but the quench from anneal has to be rapid. and pickling to assure a clean surface will be critical.
