I am looking to simplify drawing for a sheet metal component. It's a custom handle used on a standard ball valve so the tolerances can be pretty loose. The complex shape makes it difficult to clearly and completely dimension. I know that the vendor is going to use the model to laser cut the flat...
We have some 7075 AL parts that require a surface roughness of 16 uin Ra or better. It seems that the alodine coating can increase to Ra value of the surface roughness by about 6 uin. We plan to machine them to a 8 uin surface roughness to account for the coating process.
What's the best way...
Our components frequently feature threaded bosses with a groove at the far side for O-rings or as a thread tool relief. In these cases, we typically specify that the thread ring gage must contact a particular surface to ensure that the thread continues into the groove. There was a case where a...
Planning on using a SS spring in an aluminum valve assembly where the two metals will be in contact. The aluminum (likely 6061 or 7075) will be anodized. The spring would be 302 SS, or preferably 316 SS. The application will see oil or coolant, no water. Should we be considering a barrier? Is...
A customer requires that we apply MIL-PRF-8188 preservation oil on assembly that is used in the fuel system on an aircraft. Are there any standards that define the proper application process?
I have not been able to find an ASTM or AMS standard that lists a minimum yield strength for 303 SS. I expected ASTM A582 or AMS 5640 to provide this information similar to ASTM A276 for other 300 series SS. Does anyone know if there is a standard with this information?
