White Iron - Machining
#1
I have another question about White Iron. We have an application where we are experiencing high abrasion but the casting requires a machined surface in certain areas. Is it possible to machine white iron?

Thx

You could, if you really wanted to, but it will tear up tooling. We can anneal white iron down to an extent, but you lose some abrasive wear characteristics. A very long anneal on white iron is actually how they once made what was known as malleable iron, now mostly replaced with ductile iron. As-cast white iron can be more than a third chromium carbide on its own, so even carbide tooling has essentially met its match.
