Molnar Rod Steel
Quote:
Can't a rod have non destructive testing done which will show what percentage of what elements it is made of? Would say an xrf metal analyzer be able to do this? Stan

I think graphite furnace mass spectometry is used for solid elemental analysis and that is destructive.

(Yes a dedicated portion... ) Testing through-sections of Sample "coupons" would suffice rather than just the surface.
The Rod Maker ought be able to provide a Certificate-of-Compliance to SAE-4340 material specifications. Oh before we all LOL that would never happen, well why not? Should be available upon request for ANY MFGR claiming Forged Rod metallurgy is built-in to their product. The Iron-Clad Guarantee. SPS fasteners come with C-of-Cs, yet i doubt ARP will ever provide such. Yea, I said it. As for the XRF metal analyzer; they look capable! But i do not know the Test Method details. I doubt a surface scan is all ya need. I suspect a few test are involved to assess alloy mol-fraction ( watch the sparks from a grinding wheel ), inspect nucleation sizes, and the well-understood Hardness. Somehow i figure Tensile strength gets tested which should provide Yield Strength and Modulus of Elasticity. Anybody got an Instron for that. Last edited by Half-Inch Stud; 04-03-2023 at 10:33 PM. |

Fastener TQ: I use an old craftsman Torque Beam. Never a fan of the Click wrench yet I've had to use em on the job.
My stepson insisted i try/use his Snap-On Digital TQ Wrench's; OMG they are addictive during Bottom-End assy. And they are stopid-easy-capable of Angle range for finish Torque-set. The built-in accelerometers zero-out easy and provide a "meter" to show you how much angle you got, and need to get to. Intuitive after a quick intro and try.. I'd push a strong reco for the Snap-On digital TQ wrenches for achieving the more modern method of Torqueset using angle for finish TQset. I gots the SD-Rods and duh the Rod Bolts are setup for stretch gauge, yet never relied on stretch for TQset. I'd rather retain trust in a beam wrench and the oil wetting. Seems to me the best rods don't have "Nuts" so Stretch is impossible. TQ with Angle-to-finish-TQ is pretty slick. Last edited by Half-Inch Stud; 04-03-2023 at 10:48 PM. |
