NACE SP 0170 : Definition of wrought products 1

[Chumpes]

Dear all,
NACE SP 0170 states :
6.2 Industry experience indicates that low-carbon or chemically stabilized austenitic stainless steel weld overlays and chemically stabilized austenitic stainless steel wrought internals in reactors operating at temperatures less than 455 °C (850 °F) are resistant to PTA SCC.

In this context of refinery reactor internals, can the meaning of "wrought" be the opposite of "castings" ? Can an internal made from forming and welding of A240 gr. SS 321 plate materials be considered as "wrought" ?

thanks

Plate is a wrought product form. Wrought products are produced through mechanical actions (including rolling, forging, etc.) whereas cast products are poured (i.e. cast) into molds and such. In this example, the overlays would be considered castings.

I would sure hate to see cast pressure vessel plates!
