Experts: Is brass FCC or BCC at room temperature? Also, I was wondering if it was Austenite or Martensite? Specifically, the brass used in brass bearing races. Thank you.

Does anyone have a recipe for electro etching a prepared sample of Stainless Steel T-301 and Admiralty Brass? Thanks in advance.

Again, thank you. Jellopool

Many thanks to all of you who have contributed to this thread. I appreciate it. My question has been resolved. Jellopool

I have two samples that I have taken micrographs of under 100X magnification. One sample is thought to be SS T-301 and the other is a sample of an [unknown] brass bearing case. I would like to compare my micrographs with other micrographs to determine exactly what type of brass and SS I am...

On a piping assembly subject to B31.1, with a design operating temperature of 800°F, a bracket for external attachment of an instrument panel is specified to be welded to the pipe with a 3/8” fillet weld. What examination is required for this weld? When a 3” NPS branch is welded to the piping...

When PT testing a butt weld on 14” (14” O.D.) pipe a toe crack is discovered that is 3 5/8” in length. Under API 1104 can this crack be repaired using a qualified repair procedure? Under API 1104 what method of inspection must be used to inspect an area of a repair? After some digging around...

Thank you for the answer. Does this mean that 100% must be MT or PT?

Under the B31.3 requirements for Severe Cyclic Conditions, what percentage of socket welds that have not been tested by radiography or UT must be tested by the MT or PT methods? Under the B31.3 requirements for Elevated Temperature Fluid Service, what percentage of socket welds in P-No. 4 and...
