[TheForge] andiron bar replacement

[Jay Hayes]

Don,

As Frosty mentioned, I stock ITC-213 coating for protecting metal 
subjected to high heat. The coating bonds to the metal and eliminates 
the scaling that eats away at the part. As others have said Stainless 
Steel will also last longer than mild steel. I have used 309,  310  and 
some 400 series SS for industrial furnace parts that held up well. Not 
as pricy as inconel.
