Hydrogen embrittlement relief without baking
I'm a new design engineer in the product department of my company. We are currently using pre-harden steel with yellow zinc plating after sand-blasting to a depth of about a few microns. I know the common practice is to bake to prevent hydrogen embrittlement. But, there was a suggestion that I can include a waiting period (instead of baking) for embrittlement relief. If that is so, how long do I have to wait? Will it be as effective as baking? Please suggest for solutions.
Thanks,Jonathan y.h. Seet
I have never heard of waiting instead of baking.
However I have heard of waiting too long before baking stopping the baking process working correctly.
If the baking process does not work correctly the parts will fail at a lower stress than expected.
Thus the parts are then scrap.
My advice is bake don't wait.
