Regarding materials, what are the abbreviations for WPA, WPB, and WPC? That is, what are their corresponding English terms? And what does \"DUAL CERT\" in A182, F304/304L DUAL CERT mean?

Dual-grade materials, also known as dual-specification materials, such as A182 TP304/304L, require that the chemical composition of the material meet the requirements of 304L, while its mechanical properties must meet those of 304. The chemical composition requirements for 304L are high, and the tensile strength requirement for 304 is higher than that for 304L.
