Scrap steel

[cuemaker]

I have a bunch of B7 studs, 1.5 inches thick and 8.5 inches long... i have at least 50 and they weight a fair bit... plus a whole bunch of other bolts etc..

I checked into scrapping them but around here they are paying 140 ish per ton...is that about right??

Personally, I'd hang onto it. You might be surprised when you'll need them and scrap prices will probably go back up, then you can sell them. If you absolutely need the room, then 145 isn't horrible for a LTL or light truck load. Here is a list of scrap prices for today:

Yeah...what you have there is some cheap bar stock about 1.25" in diameter I would guess

Edit-- just looked up these spec's:

Looks like there is some Manganese content in addition to the chromium and moly so this may be really tough to machine. I don't know just how high the MN content has to be before it really toughens things, but I do recall that train rail is high in Mn content and its tougher than...well...B7 studs :-)

B7 studs are about the same thing as 4140.

Then you may have Pre-Hard. This is likely a valuable material- bits o barstock.

You might anneal them or you could use them hard as they probably will cut with carbide even hard- Grade 8 cuts, slowly.

Peel the threads off with carbide and use whenever a piece of high strength weldable steel is needed.
