I talked to our test lab guy about what we used in our old fuel test stand. In the ancient past, we used MIL-C-7024 calibration fluid. Because it became unobtanium, we switched to low aromatic Stoddard Solvent, more commonly known as zippo lighter fluid or dry cleaning solvent.

Thanks for the info guys. To reply to some of your comments: EdStainless, the leaks are generally axial, about a 5/8 inch from the part centerline. We have had a very few at the weld joints. FYI, I will be contacting your company about 430 tubing. We make a lot of solenoid housings from 430 bar...

I am looking for a source of 430 stainless steel bar, approximately 1.5 inch diameter that, when tested to ASTM E45, Method A or D, must have an inclusion rating of 1.0 or better, (2.0 may be acceptable). I have been told by one source that, historically, the only way to achieve this rating is...

Do the "save as" to a bmp but go to options and increase the resolution to about 2400. Makes a huge bitmap but open with an imaging package and save as jpg. Better yet, go to www.cbliss.com and download his utility for directly outputting to jpg.

The requirement for numbering each dimension on a print for inspection generally comes from the requirement for traceability, which is common in aerospace work. You must be able show that each...

We weld this combination quite often. The low carbon grades (304L or 316L) create a better weld. We use only 430. We do not use 430F for welds. I know other companies use TIG and Laser, but we use only E.B. We do not use fillers but keep gaps to a minimum of .002". Parts also have to be...
