I've decided to begin selling off some of my bearing grade steel (I have about a dozen rings from 6" diameter up to about 14" diameter. Soon you'll be seeing threads with 52100 rollers being sold. I'm also going to be cutting up my bearing rings and selling it in different sizes. The reason for this thread is to help me decide what sizes and shapes would be best for me to cut them and forge them into. I'm know that many of you have power hammers and presses and would only like to purchase an entire ring or section of a ring and do your own forging. Others, especially those of you that don't have power hammers and presses, would probably like to purchase rollers, flat bar or round bar. I can forge them to any shape and size.

I've attached some photos of some of what I have.

I'm asking for guidance, to help me decide how to prepare the bearing rings for you. If you're interested in this steel, would you be most interested in:

  • Sections cut out of a ring?
  • Flat bar? If so, what size would you like to see it offered in? Stock removal makers would probably like to see a different sized flat bar than a forge maker would like to see.
  • Round bar? If so, what size round bar.

I'm going to be sending a sample of each ring in for analysis to determine the exact steel type and will provide the chemistry with each purchase. The materials that I'm expecting them to be are 52100, A485-1 and A 485-2. When offered for sale, the steel will be identified in the for sale thread. I'm including the chemistries of what the three steels are for your information. The heat treat for all three steel types is the same. Just treat all three as you would 52100. The 52100 is the shallowest hardening steel of the three and the A485-2 is the deepest hardening steel of the three.

A485-1
Carbon 0.90 / 1.05
Manganese 0.95 / 1.25
Silicon 0.45 / 0.75
Chromium 0.90 / 1.20
Nickel 0.25 Max
Molybdenum 0.10 Max

A485-2
Carbon 0.85 / 1.00
Manganese 1.40 / 1.70
Silicon 0.50 / 0.80
Chromium 1.40 / 1.80
Nickel 0.25 Max
Molybdenum 0.10 Max

52100
Carbon0.93 / 1.05
Manganese 0.25 / 0.45
Silicon 0.15 / 0.35
Chromium 1.35 / 1.60
Nickel 0.25 Max
Molybdenum 0.10 Max

I'd take some flat stock in any of the listed steel in 1/4" x 2".
Thanks,
Mitch
 
Maybe I won't be cutting it up and forging it after all. Doesn't seem to be much interest. I'll give this about a week for feedback before deciding whether to cut up and forge them out.
 
This seams like it would be a great source of 52100 to me. Especially for the forge guys. Maybe y0ou should just list it by the pound for the forge guys Scott.
 
Hey, if this works out for you Scott, let me know... I've got about 750 lb. of this stuff :) I'm not nice like Scott though... I have no plans of forging it down for anybody :D

Hmmmmmm...Well, I guess I can't ask to come and pay for time in your shop to forge it down.

Actually, I was going to forge it down at my neighbors. He has a power hammer that I can use. We have an arrangement that works out very well for both of us.
 
I would be very intersited in a bunch of this to forge down for my self. so if Nick or Scott want to let me know what thy would want per pound that would be great.

Jarod,
I'm traveling this week, so won't be acting on this until Friday. I'm going to be posting a bunch of rollers for sale on Friday. They are a size that don't need to be worked down much. You can just weld one onto a piece of rebar for a handle. Each roller will make 1 to 3 knives, depending on the size rollers that you purchase.
 
Hi Scott,

I'm interested in the 52100. It just depends on how much. (How much you charge and how much $ I got. :D) Anyway, I'd like stuff in the 1/2"-3/4" diameter range for hand forging. And/or, if you forge out some flat stock, something like 1/4" by 1" or so wide.

Thanks, Phil

I haven't worked out exact prices yet, but it will be very reasonably priced. Straight rings and rollers will be the least expensive, since they require very little or no work to prepare. The flat stock will be a little more per pound, since I have to forge it out of the rings.

I'm guessing it would cost even more if you forged into into blade like shapes! :p:p:p:p:p:p:p:p
 
Just want to make it clear that I was NOT trying to horn in on Scott's mojo. I just figured if this all worked out for him then maybe I'd look at unloading some when/if Scott slows up on it.
 
Wednesday, March 4 is going to be forging of rings day. So far I see the hoped for sizes as 1/4" x 1" and 1/4" x 2". I also see 1/2" to 3/4" range on the forging stock. Any other size requests. I'll also be offering some cut ring sections for those that already have a power hammer or press that would like to work the material down themselves. All of this ring material will only be offered after I've sent a sample out for Metallurgical Analysis.

Sounds GOOD Scott, THANKS!
 
I'll be letting you know more in the near future as to the actual cost. It's probably going to be in the $6 to $9 per pound range for rough forged to flat bar shape, but don't hold me to that, until I figure out how much gas, etc. we're using to forge this to size.
