Can anyone provide approximate or typical Charpy impact toughness results for A514 B / T-1 steel in temperature range of roughly about +32 to +70F. Thickness range about 1-2 inches. I have found information on transition temperatures but I need an estimate of Charpy ft-lbs for the approx...
The volunteer staff at a local air museum are doing an analysis of recurrring cracking on a 1940s vintage Franklin engine. The A242-T21 cast aluminum heads are threaded onto a cast iron cylinder. We can't find elevated tempertaure tensile properties (Yield and UTS) for the A242 in the T21...
Can anyone provide typical tensile yield and ultimate tensile properties for A242-T21 aluminum sand castings? Temperature range of interest is up to 400 deg. F. I have only found room temperature properties for that particular heat treatment. Application is a 1940s vintage aircracft engine...
The API 1104 pipeline welding standard includes an option (Appendix A) for use of a fitness for service or fracture mechanics-based approach for evaluation of girth weld flaws in new construction. Is there any parallel option for new construction welds made in B31.1 or B31.3 piping? In my brief...

The scope of B31G "Manual for Determining the Remianing Strength of Corroded Pipelines" does not include reference to B31.1; it only references B31.4, B31.8, and B31.11. What methods are acceptable for determining the minimum acceptable remaining wall thickness for localized internal corrosion...
