There are any number of other materials besides sand that can be employed that
generate much less heat. Sand is preferred b/c ir's cheap and gets the job
done. But I agree that it would be difficult to generate enough heat to cause
tensile strength loss.

Subject: Re: [Healeys] Powder on Springs
Ham fisted sandblasting
will always cause damage. To generate so much
heat while sandblasting these
springs must have taken quite some effort.
Always use a fine grit or glass
beads and moderate pressure and check
the heat regularly in the springs while
at the job. It should not cause
any problems at all, unless the springs are
so rusted that they should
be renewed anyway.
