    Coupon Testing for UHA Materials

    Thanks SnTMan & metengr. I agree with what was said regarding UHA-51(a)(1). Charpy was just my example. I was also wondering about tensile tests, too, but you have also answered that.

    Coupon Testing for UHA Materials

    UCS-85 is a specific section of Sect. VIII, Div. 1 that addresses the required heat treatment of test specimens for UCS materials. What is the equivalent of this for UHA materials? For example, if a part will be solution-annealed (additional to SA by the mill) and requires a charpy test, does...

    Required Minimum Copper Content

    I am still not understanding why this would be in the specs for mild steel materials, such as 414G, for example, if a customer could/would simply just specify a copper-bearing steel (Monel or other) if necessary for their job. I guess I could just assume that they would want the benefit of both...

    Regarding minimum copper content requirements for some materials in ASME Section IIA, how does everyone interpret "when copper steel is specified?"

    Filler Substitution

    I have a SMAW WPS that is meant to be used for welding with E2553 filler or an allowable substitution, per Code. I want to use E2594, instead, but am not sure if it is permitted because E2553 does not fall into a specific A-number designation and the A-number is an essential variable. The...

    Filler Choice for 410S

    Do 309 and 309L fall into the category of "austenitic-chromium-nickel", as referenced in UHA 32-2? I would believe so myself, but I am not 100% sure how to determine whether or not a filler falls into that category. Also, what is the best way to determine which of the two is best for the job...
