I've a couple of fastener suppliers that are claiming it's technically acceptable to perform wedge tensile testing (IAW ASTM F606) on a fastener that had been previously yield tested (but not to failure, obviously).
My position: yield testing of a fastener imparts at least limited work...
I’ve a situation where C-steel flanges to ASTM A105 are required to be manufactured from individual forgings; however, we’ve discovered (AFTER the fact, of course) that one vendor did not properly read our procurement documents and as a result we have flanges that were machined from either...
I haven't had a need to evaluate HT creep since I studied it in grad school, many years ago, and today I was asked a question regarding high temperature creep of carbon steel. The application is a steam plant, and the question pertains to installing carbon steel by mistake.
Any suggestions on...
Any recommendations on “planners”, both hard copy and electronic?
Here’s my history, thoughts, and desires:
1. I’ve used in the past DayTimers, both small and medium size. While I saw many advantages, I found replacing and storing a large volume of paper every month a pain.
2. I often use...
I'm investigating leaks caused by pitting on a fuel system constructed from 304L stainless steel using 308L electrodes.
The system occasionally sees dirty “river” water, occasionally treated fresh water, and may even have fuel contaminated by salt water. The result has been pitting and...
Does anyone have data or thoughts on the pitting performance of Type 304 stainless steel versus Type 304L?
Are they expected to be similar, or is one significantly different?

I’m starting a corrosion study (my specialty) and need to consider the soil and “recharge" of the soil (NOT my specialty)
I’ve have data sources that discuss the moisture of soil (and other parameters) in terms of percent and resistivity (and conductivity, of course), and these...
I need to ID a non-flammable fluid with a specific gravity similar to gasoline (sp ~ 0.74). It's to test a float that's part of an alarm system and needs to be "safe to handle", hence non-flammable. I don't know the details of the alarm, I was just asked a question.
Thanks for any suggestions
