Pits in Peeling


2000

I am facing a problem of light pitting type defects after peeling and grinding of carbon steels.

These defects are not visible but show up in Magnetic particle testing

Any suggestions

Prassad:

Some loose abrasive mechanical finishing processes, especially the high energy variety might be helpful in blending and closing up the pitted surfaces you mention. Much would depend on the type, size and production volume of the parts you are working on, which is not described in your statement of the problem Dave Davidson
