    Does impact toughness depend on diameter?

    If there were multiple diameters of bar made from the same heat at a mill, would the mill perform a Charpy test on each individual diameter bar or would they just test one representative sample from the entire heat/lot? Meaning would they machine the same size charpy sample from two different...

    bar bending max radii

    Is there a formula to figure out how much stresses would come into play when bending a solid 5/8" non ferrous bar, specifically n04400? I want to know if it would crack?

    HCl and HF, in the same piping system

    In a piping system that will have 36% HCl ran through it and then purged with air and then 6% HF run through at ambient temperature, would you expect any issues using C276? Or possibly another alloy? I am thinking C276 just because its resistance to HCl but not so sure with the HF, I know it is...

    Nitric, sulfuric and Hydrochloric mix?

    If a there were an acid mixture containing( Nitric, Sulfuric and Hydrochloric) what would the corrosion behavior of the mix be? Oxidizing? Reducing? I don't have any concentrations yet. The obvious thing would be that the acid with the biggest presence would take precedence over the others, is...

    Cleaning Alloy C22 with dilute Muriatic Acid?

    I have some tubes, with some tarnish and handling stains on it, I have heard from a colleague that you can use a dilute muriatic acid solution to wipe away the grime. Has anyone ever heard or tried this?

    Pickling stains..

    I have some Alloy C22 that has some blackish stains around the length of a tube. The pipe looks smudged and foggy and the dark stains are not in any particular pattern down the length of the pipe. If they are pickling stains, this would not affect the corrosion resistance of the pipe, correct...

    ASME code case 1192 regarding k500

    I know K500 is made to QQN286 Rev E,F or G, and ASTM SB 865. But someone is asking about ASME Code Case 1192 in regards to K500. I do not know what is meant by this, any thoughts? Does it reference the chemistry or mechanical properties, like B865?

    Dichloroacetic Acid (2.5-10%) in Toulene

    All I have on this media is an MSDS, no temperature. Does anyone know of somewhere I could find some data on how this media attacks. I haven't been able to come across this, but I know it is very nasty and caustic. I have found some information on Toulene, but not toluene contaminated with DCA...

    "laminated" hastelloy??

    Has anyone ever hear of Laminated C276 bar? I have someone asking for this and I have never seen this. He is also asking for hard/stripped solubilized. Are these surface treatments or something, or is this guy just confused?

    Hydrofluorosilicic Acid/Fluorosilic acid and HF(aqueous)

    Does anyone have any experience with HFS(FSA)? I am trying to figure whether or not, corrosion data will be close to that of aqeous HF against Ni-Cr-Mo alloys like C276. I know Monel 400, is highly resistant to HF, and I have found some data to show that C276 and monel are good, but also...

    How would I figure the load/weight capacity of a homemade cart used to move around heavy alloy bars?

    We have some utility carts that our warehouse uses to move around heavy alloy bars and pipes. These carts were homemade many years ago and now need to be rated by capacity. Any idea of where I would start in figuring this out? I can get the material properties no prob, but I don't know where to...
