We used to cast notches in the feeders and risers then break them with hammers. They almost always broke at the notches.
This stuff is really hard to cut. I assume that you are using it for abrasion resistant parts in a mining application.

i think in the notches, for me is the only way for cut the riser so, how i can improve the surface for macro etching?
thanks

Offhand I haven't seen anything that big sectioned as your scribe line.
Is there a rock quarry near you that uses abrasive cable for cutting?
They also might b able to to polish your sectioned
One other possible is use something like a Blanchard Grinder. The only problem is that you will loose 1/2 to dust.
RE: Help with High Chromium White Iron As Cast
A second alternative would be a BIG rock saw, like unclesyd suggests, see if a local granite quarry can help you out.
RE: Help with High Chromium White Iron As Cast
If you could find someone that uses a bridge type blade saw to cut Granite.
WF Myers is one maker of abrasive cable saw. As posted before you need to locate any one in the stone mining or cutting business.
You will still have to use a surface grinder to give you a suitable finish which I think will be good enough. If not look to Granite and Marble polishers.

As your piece is so big you might want to dice it into smaller sections and the split in smaller sections. You are cutting the hard way.

Just to give you a little more insight on stone saws that are out there. Here are some big ones in China but there others out there..

Look for a heat exchanger repair facility.

If you have a metal service center near you check with them for the type saw the are using. Again you will have to buy blade.

The is the correct version of my last post.
You might be able to find someone with this type endless loop saw from Well Diamond,
Quote from their website
"The Model 7243 can accommodate parts as large as 470 mm high
x 470 mm deep (18.5 x 18.5 inches approx.). Length of the part is unlimited as long as the part can be supported.
The Model 9245 New. "

As it appears that you deal with thick cross sections you might want to file the information.
