Recommendation? Can anyone help me identify which material is better?

I have 2 different steel material and got them both tested. Following are the results. However I am not sure which steel is better from both of the comparison. If anyone can help me out to identify it, I will really appreciate it.

Sorry for the bad quality.

Kind Regards,
 
Were those some scrap metals you found where you didn't know which steel it is exactly? Because if so I am not sure it was worth the trouble.

Anyway for someone to tell you something about which alloy is better you first need to specify for what purpose you want to use them.

Thank you for prompt reply. Well its like i have an original part (sample A) and i asked someone to make the similar part (Sample B) so he made it however after i tested the material the results were different. I want to know if the material he used is better then the original material or worse. And I am not sure if that can be determined by the chemical composition of the material. If you have any idea in general which is better in terms of strength or wear or tear or if you can tell me in general that having higher carbon or having lower nickel is better? Thanks again

I am no metallurgist, I can not tell you which steel is better based on the chemical composition. But even If I were, it would still very much depend on what the part is, what it is used for and if the heat treatment is optimizied for that use.
 
My guess is that they will be pretty equivalent.
A will be slightly tougher and B will be slightly harder, but the net effect should be roughly the same …. depending on the intended use.

Thank you for the reply. I understand it however I was talking in more general that is it possible to know from the material composition which material is better. The part is basically a gear used in harvester.

Thank you so much.
I am little confused, when you say it should be roughly the same. so the composition does not makes much of difference then?

Are you planning on putting it back in a harvester? What the guys are trying to tell you is that there is no better, there is just differences. This site is about knives and there is major discussion about those subtle differences in performance. You would think that a knife is a specific thing but we use vastly different steels for different sizes knives vs intended use vs material cut vs a pile of other things.
I can tell you the proper use for many weldible products and there are a lot of guys can tell you the best use for knives. Maybe there are some guys here who know about harvester gears if that is your intended use.
 
If you are making a harvester gear, this material may be what you are after... I have little knowledge in that arena. I don't think you are making gears.

What I do know for sure is that this material(both) will make a poor knife. Depending on the stock size, Sample B might make a decent hammer.

If it's for an International Harvester, "A" is better. If it's for a Gleaner, then "B" is better. Because midichlorians.

Unless you're harvesting in Canada, mon frère. Don't forget that bit.
Easy answer... trace it back to the original heat from the mill.
 
Yes, the composition matters, but the differences in these two steels isn't night and day. It is more like 3PM and 4PM.

What I was saying was that B would probably be a bit better in hardness and have good toughness. B should do the job of the original part just fine.
