How much machining can 410SS take before it starts to change
How much machining can 410SS take before it starts to change
(OP)
A machine shop ordered the wrong size material and I'm trying to find some information on what the effects of machining material very heavily are.
Material is 410 SS in the quenched and double tempered condition for NACE service, HRC 22 max/BHN 207-235. Bar stock is 5" dia and will have to be machined down to 3.47" dia. I'm worried about the effects of removing this much material and how it will effect the strength/structure of the 410SS.
any info on this would be great!

The only alloys in which I have seen this effect were Cr:Mo low alloy.

However, if you wanted to avoid any kind of troulble ,you could stress relieve the bar after the last step of machining.Obviously,if bar were bended, you have to straight and ,then, stress relieve. Temperature of stress relieving has to be 25°C under the tempering temperature. If this temperature weren't shown in certificate, the Supplier of steel must kindly declare.
