Laser blanking .005" thick spring temper 301 stainless
Laser blanking .005" thick spring temper 301 stainless
(OP)
I'm designing some parts with this material that need to be blanked and formed. I expect in production the blanks will be stamped. For prototypes and perhaps initial production I was thinking laser would be a great way to produce blanks. Are there any metallurgical effects I should be concerned with regarding lasered edges in a fatigue application?
Thanks in advance for any advice.

If you are expecting edge initiation of fatigue cracks, the two parts will not be alike.

EDM is frequently used instead of laser cutting for prototyping parts out of spring steel strip. We have used this successfully for similar applications, although the same kind of defects are present as with laser cutting-- change of microstructure near the cut edges. However, if you do not intend to perform durability testing that involves > 10,000 cycles, then this can be a method for obtaining quick prototypes.

Would vibratory deburring or tumbling effectively remove the heat affected area from laser or edm parts?
israelk, Chemical etching would be a process similar to producing electronic circuit boards, correct?

finsihing is VERY important for the life of both prototypes and stamped production parts. The cold work of stamping leaves a tesnsile residual stress on the edge. Finishing can convert this tensile stress to compressive.
