I've never heard of anybody scraping mild steel, but what do I know. My
opinion is that mild steel is not stable enough to hold the precision
that one is scraping for. CRS especially has internal stresses that
would make it unstable.

But "scraping" is simply the removing of small amounts of material
with a "scraper". I've scraped babbet, bronze, cast iron and steel.

You're right. I was thinking in terms of using the OP's straight edge
to scrape machine ways, for instance.
