Snow plow cutting edges

Ok, I searched the forum and can't find a discussion specific to these.

Question--would they be heavy melt, or P&S?



A couple of them are 1/4" thick, and the others are 3/8". They're off your garden variety Western or Meyers pickup truck size plows, and of course, I'll cut them down to "prepared" size.

Thanks.

I get quite a few off tractors and other equpiment and it all goes in my heavy melt.

Ok. I asked, cause I wasn't sure whether it met this spec or not:

231 Plate and structural steel, 5 feet and under.

Cut structural and plate scrap, 5 feet and under. Clean open hearth steel plates, structural shapes, crop ends, shearings, or broken steel tires. Dimensions not less than 1/4 inch thickness, not over 5 feet in length and 18 inches in width. Phosphorus or sulphur not over 0.05 percent.

Cause if it was originally a big plate, and cut into snowplow edge sized strips, I could see where it might be.

Oh well.

Thanks, guys, for quick replies.

(I'm gonna ask at the yard anyway.)

I just realized I hadn't provided an update on this question. (For them that will seach for this question, and read this thread for the information, someday in the future.)

The yard I asked said they'd be heavy melt, not P&S, because of the chemistry. Cutting edges are a hardened steel, and that's different than P&S.

I would double check and make sure the blade isn't made of tungsten carbide. If it is that stuff brings $8-$10 a pound.
