Rats and Dogs are obviously not on the same learning and interest level as us hogs.

I posted this on their forum and got no responses. If I had posted the same thread here, there would probably be several responses in the first 5 minutes. I guess we like knowledge more than they do:D you would think that would interest them:D


Here is what I posted:

The secret to SR101 and SR77 is no longer a secret like INFI hasn't been for some time. Here is the info compared to it's relatives. You decide.

So here is what I found using Niton XL2. Not mine obviously. Very expensive device.

SR101
LEC = 1.22 Elements with atomic number lower than 17 (1% C, 0.22% Si is likely here)
Chrome = 1.46
Manganese = 0.69
Copper = 0.27
Fe = 96.36

52100
Carbon = 0.98 - 1.1
Chrome = 1.3 - 1.6
Manganese = 0.25- 0.45
Silicone = 0.15 - 0.35
Fe = remainder

So SR101 is very close to 52100. If you take Lec and subtract 1% Carbon from it, then the remaining 0.22% is likely silicone. SR101 has copper in it. It also has considerably more Manganese. Certainly this is close to 52100 with only minor differences. 0.34% more Manganese than 52100. It has 0.27% copper which 52100 does not. That is 0.61% more elements than 52100.


SR77
Chrome = 3.0
Manganese = 0.74
Molybdenum = 1.39
Vanadium = 0.24
Fe = 93.15
LEC = 1.48 Elements with atomic number lower than 17 (.5% C and up to 1% Si is likely here)

S7 Steel
Carbon = 0.45 - 0.55
Chrome = 3.0 - 3.5
Manganese = 0.2 - 0.8
Molybdenum = 1.3 - 1.8
Vanadium = 0.2 - 0.3
Si = 0.3 - 1.0
Fe = remainder

As with SR101 above if you remove 0.5% Carbon from LEC, then the remainder is silicone. So SR77 and S7 appear to be the same steel.

LEC are elements that do not show up on the analysis due to their low atomic number. Usually 17 or less.
 
Very interesting, I had read that sr101 was tweaked 52100,,, but had never really heard what Sr77 was based on,, thanks!
 
If I remember correctly you had also done an analyst of INFI a while back? Was this the same machine used?
 
Interesting. I lurk the Scrap Yard forum quite a bit but I guess I missed it. Thanks for the info!
 
First of all you didn't post it in the Yard. Second I didn't really see the point when reading it over in the swamp. Don't we all know what the steels are based on but it is the heat treat that makes a difference?
 
Wow...so the special sauce is in the Anneal. / Temper. / Quench then, I assume? :o

Copper's gonna add toughness, right?

Hey you're not trying to sneak in .0001% Co there are you Cobalt? :p

And about our other kin...I've noticed threads with lots of colorful pictures do pretty well over there ;)

They're a little touchy about their "reading comprehension."

You got your replies but my guess is the Dogs and Rats are more knowledgeable about their steels.
 
You mean this information has been out there this whole time?!!! I guess there wasn't enough pichurz for me to get it.
 
Always nice to have additional trials from an independent lab...thanks Cobalt...

interesting threads from over a dozen years ago too...makes for fascinating reading...and I thought elephants had good memories, the dogs & rats are giving em a run for their money on a Monday nite
 
I'll remember never to mess with dogs and rats ;) their kinda mean

Seriously though, There has been tons of threads regarding people wanting to know the elemental analysis, and when someone says added kryptonite, no one really knows what that means as it was never defined. So there you go, it either proves what you knew all along or it surprises you. SR77 did not surprise me. SR101 did. I was told it had much more Cr in it.
 
Nice job, Seth, for digging that stuff up. I thought this was fairly common knowledge for the Bussekin faithful.

Most of us that have been around for more than a few years can remember when Swamp Rat and Scrap yard had that information on their websites. Unfortunately, it didn't carry over to the new websites.

Anyway, I am thankful for this independent analysis.

I miss some of that info from the old sites.

Always read it as the kryptonite being the heat treat. But now thinking about kryptonite is it made Superman week. So the Man of Steel weakened around the stuff - maybe a poor choice of words. Or it could be the kryptonite destroys all other steel but not Busse.
 
Maybe Swamp Rat and Scrap Yard identify more as Batman rather than Superman, just in case Superman needs to be straightened out.
