Cold Drawn / Rolled Alloy 20 Welded Nickel Alloy Tube ASTM B468 UNS N08020

Cold drawn/rolled ASTM B468 UNS N08020 Alloy 20 welded nickel alloy tube

1. UNS N08020 Alloy 20 welded tube 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.

3. What is the difference between cold rolled and cold drawn?

In terms of mechanical properties, cold drawn steel does not possess the superior hardness and smooth finish achieved by cold rolling steel. ... Cold drawing steel also results in a comparatively rougher surface finish, with less uniformity in the mechanical properties from the rod moving through the die.
