Carpenter® Alloy 20Cb-3®
Carpenter® alloy 20Cb-3® (UNS N08020) Ni 35, Fe 37, Cr 20, Cu 3.5, Mo 2.5
Excellent resistance to chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Resists pitting, crevice corrosion, SCC, and intergranular attack.

Pickling tanks, gas scrubbers, piping, heat exchangers, pumps, shafts and valves. Synthetic rubber, pharmaceutical production and other process equipment.

Alloy 20 is a highly alloyed iron-base nickel-chromium-molybdenum stainless steel developed primarily for use in the sulfuric acid related processes. Besides sulfuric acid related processes, some typical corrosion resistant applications for the alloy include chemical, pharmaceutical, food, plastics, synthetic fibers, pickling and FGD systems plus many others.

Although normally considered a stainless steel, it has been classified as a nickel base. UNS N08020
