UNS N08020 ASME B16.47 Blind Alloy Pipe Flanges Forged Series A B Size 2'-24' DN300
Alloy 20 flange between ASME B16.47 Series A and B
Take 48” 150# WN flange for example, we can get conclusion Series A price is much higher than Series B. So when you ask large size flanges, you'd better mention which standard clearly.

UNS N08020 Alloy 20 flange material introduction:
Alloy 20 is an austenitic stainless steel developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries. Alloy 20 resists pitting and chloride ioncorrosion, better than 304 stainless steel and on par with 316L stainless steel. Its copper content protects it from sulfuric acid. Alloy 20 is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless. Alloy of the same name with the designation "Cb-3" indicates columbium stabilized.
