Hi, I have a drawing that calls out ASTM E1417 Type I method A, form d, class 2. Is solvent remover class only specified on ASTM E1417 Type I, Method C or could it be specified if "form d" (nonaqueous) developer is used?

In AMS 2774, does anyone know what the metallurgical reason for the higher annealing temperature at 2050 F temperature for alloy 625 if brazing will follow? Normally, annealing would be at 1900 F, but footnote 9 in rev G requires a 2050 F anneal if high-temperature brazing is to follow.

Does anyone know a good resource for searching for manufacturers of titanium metal matrix composites?

Either cold worked or annealed. I need to be able to convert between microhardness (Knoop/Vickers) and Rockwell.

Is ASTM E140 Table 3 (high nickel alloy) the appropriate table for converting microhardness to Rockwell for 304L stainless steel?

Where do I measure underfill from when I have mismatch? In this attached figure, should it be "A" or "B"? I can't find guidance in AWS D17.1.https://files.engineering.com/getfile.aspx?folder=37b4d1fb-93dc-447a-9062-0c9789ce55f6&file=welder_cert_7773.jpg

The main issue is not whether there are capable facilities but more if they are willing to do only one part.

I am having trouble finding a supplier with the capability of making large diameter (~55 ") flash welded rings in high temperature alloys such as RA 330 and Inconel 601. Does anyone have any suggestions?

Does anyone know where I can find hydrazine compatibility with silver plate and TiN coating? I couldn't find it in MAPTIS.

Hi MagBen, Our material is in the cold worked condition. It operates in the 600–1000 °F range.

I am having trouble finding creep curves for Elgiloy. Does anyone know a good resource?

the all around symbol is not the issue. Please see clarifying diagram. The issue is the arrow side and other side references. https://files.engineering.com/getfile.aspx?folder=28086e4a-953c-44ae-a65f-d877ef3b9d76&file=New_Microsoft_PowerPoint_Presentation.pptx

Would you interpret this symbol this way or is this incorrect? Should I have two symbols instead?https://files.engineering.com/getfile.aspx?folder=bde4cf37-a233-4c4c-abee-79fda1bd023e&file=New_Microsoft_PowerPoint_Presentation.pptx

We have it in the annealed and then cold worked condition. I am only able to roughly estimate the % cold work based on the microhardness.

I was able to obtain charpy data for cold worked inconel 625, but don't know of a good correlation from Charpy to Kic or Jic. Anyone have any suggestions? I know there is a correlation for steels, but I have nothing to say whether that is applicable.
