identifying steel - color codes
"xray" wrote in message ... I have some random steel rods I picked up locally. I'm not sure of the material. Two of them have colors painted on one of the ends: red on one and orange on the other. I'm wondering if these colors tell me what they are? Color codes are not standardized, so unless you have the code from the particular source, the colors won't tell you much. Harold |

The entry for 12L14 says "black and white". I assume that means it could be either, rather than it should have both. That entry bothers me because I bought some 12L14 end scraps from eBay and things don't seem to match the table I found. Some are white, which does match, but a couple are copper color and one is red. Is the color code a useful way to identify scrap steel? Is there a better reference on end colors somewhere? Can anyone tell me what my two steel rods with red and orange ends probably are? Thanks for any enlightenment you can share. -Rex I received over a ton of steel rounds of all different sizes. I deduced that some was tool steel as the company made some dies for their operations. I stamped a code number on each round and sliced off a wafer and stamped the wafers with the same code. I heated each wafer red hot and dropped it into quenching oil. Then I could tell with a file what was cold-roll and what was tool steel. Next I spark tested each tool steel wafer with a known piece of O-1 and D-2. I feel pretty confident with categorizing each piece. I also knew there wouldn't be too many odd-balls. I only have 2 that I'm not sure about exactly what they are but they hardened. Do you need to know what the alloy actually is? Or will knowing general properties do? Try turning a whack of each piece with HSS tools, you'll know by the way it cuts and the finish it leaves. You can even tell by the smell of the cut. Don't even think about sending samples to a lab for $4-600 a pop. |

Oboy,,, Years ago we had a machinist who was not exactly a rocket scientist. We did a lot of SS, and generally from this vendor the color codes were predictable. The guy was looking in the stock bin for a piece of 316...we noticed the blue end, and it was one of those afternoons where people were feeling humorous. We told him, "Just breathe on it and smell it quickly when it is moist...you can detect the "tang" of nickel!" "Look!( Noticing an orange code) You can even smell the sulfur in this 303, and in this 17-4 (Grey/white) the aluminum in it makes it smell just like 6061!!!" We walked away, and had a good laugh. A couple of days later, the guy who ran the place, a good mettlaurgist in his own right, walked by, and saw this guy smelling the stock, one piece after another. He walked up and asked him what he was doing. From a distance, we could see the rocket scientist trying to explain, gesticulatiing and thrusting pieces under the boss's nose. The boss just stared at him silently, and walked away. We got to the other end of the shop ASAP, collapsing with laughter. |

OH MY GOSH!!!! Now THAT was a riot. Reminds me of a good one...Here
goes: I recently retired from the army. After 25 years in the military as a welder/machinist, it's safe to say I've met some pretty colorful folks...one of them was a guy by the name of Vern back at Fort Knox, Kentucky. I was the sergeant in charge of the shop & "corpral Vern" was one of my not too bright welders who couldn't get through even the smallest of tasks without getting really confused. He and one of my sergeants finally had it out about Vern's inability to work on a project without it turning into a disruption for the whole shop. I had recently undertaken a project where we were about to begin taking a bunch of M60 battle tanks into the shop, draining all the fluids, removing the transmission & engine and cutting 4" holes in them before putting them back in, welding up all the hatches & plugging the barrel, painting the tank green with a white star and shipping them off to VFWs for use as a display tank. After the 1st tank had arrived, I was away from the shop for awhile taking care of some business. As I was walking back into the shop, I notice Vern out front standing on this tank....tapping it iwth a hammer...nodding his head up & down (as if to say "yes" to himself...Vern talked to himself a lot) and marking an "X" on the tank with a piece of soapstone. I look over closer to the shop....and all the guys are just rolling with laughter! Now before I go into this any further, you have to understand that the armor on these old tank turrets is thicker on the sides than it is on the top...like wise the hull is thicker on the front and sides than it is on the rear. This tank has soapstone "X"s all over it and Vern is just happily tapping away! I climb up on the tank & before I can say anything, Vern says, "That's right you know what I'm doing don't you sergeant? See people who wrok for you get smart, and then someday we get your job!" I can hardly contain myself as I admit, 'This must be something old sarge forgot, why don't you show me?" Vern says listen..."Tap, tap, tap (on the side of the turret with the hammer...and then..."Tink, tink, tink (on the top of the turret) you hear that difference sergeant? That's a soft spot in the armor!" then he beams "Segeant Troy showed me that!" Vern was so proud of himself...it was almost hard to explain to him, he'd been the butt of a joke. I kept the piece by helping him play a joke back on the good sergeant. -Wayne- |

Oh, it's not THAT easy, you have to smell it while it's cutting...everybody
knows that! "Grunty Grogan" wrote in message ...

According to xray :
I have some random steel rods I picked up locally. I'm not sure of the material. Two of them have colors painted on one of the ends: red on one and orange on the other. I'm wondering if these colors tell me what they are? If you can tell us which steel vendor they originally came from. Really -- each vendor has his own set of codes. I could look up the ones which Jorgensen steel uses, but I don't have a convenient source for the others. I found this link... http://www.southerntoolsteel.com/color_codes.html which lists color codes, but I'm wondering how trustworthy it is. The entry for 12L14 says "black and white". I assume that means it could be either, rather than it should have both. Nope -- it should have both. (Otherwise, they would have said "black *or* white", not "and". This is because there are more steel alloys (and other metals) than there are reasonably identifiable colors, so they have to use two (or sometimes even three) colors to mark the metals unequivocably. Jorgensen has several where there is a primary color plus a stripe of another color. And the Jorgensen catalog lists a lot more metals than your web vendor does. And this is only for metals from this one vendor. That entry bothers me because I bought some 12L14 end scraps from eBay and things don't seem to match the table I found. Some are white, which does match, but a couple are copper color and one is red. Again -- from different original vendors, so you can't expect the color codes to match. Is the color code a useful way to identify scrap steel? Nope -- because with scrap, you are unlikely to know who the original vendor is. Now -- you could pick some vendor's color code chart to which you have access, and paint any incoming steel which you can identify to match. Is there a better reference on end colors somewhere? The problem is that there are *lots* of them. And they all disagree. :-) Can anyone tell me what my two steel rods with red and orange ends probably are? *If* it came from Jorgensen: Red 1040/42/45 Orange 1213.1215 Black with White stripe 1035 Brown & White Leaded Grade A (Ledloy A, La-Led) (their 12L14) Green Leaded Grade B (LedLoy B, Super La-Led) Pink & Purple Leaded Grade AX (LedLoy AX) Thanks for any enlightenment you can share. Well ... I'm sure that this is not what you wanted to hear -- but it is the real world, so I'm afraid that you are stuck.

It would appear that most if not all suppliers have their own color codes. Ive got machine shops with 3-5 color code charts on the wall side by side..and non of them match. This sucks of course..but...thats the way it is. Shrug Gunner "Pax Americana is a philosophy. Hardly an empire.
