M2-M72 Alloy 20 thread rod full threaded stud bolt DIN975 DIN976

1. UNS N08020 Alloy 20 thread rod 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.
