(Alloy 20 UNS N08020,
W.Nr. 2.4660, Carpenter® 20, 20CB-3®)
Description
Alloy 20, W.Nr. 2.4660
is an iron-base, austenitic alloy with excellent corrosion resistance to a
number of different media and proves to be useful in a number of applications
such as flue-gas desulfurization, chemical processing, food processing and
storage as well as pharmaceutical applications to name a few. Application of
the alloy could result in real cost savings when carefully compared to
higher-cost alloys to determine if the necessary resistance is obtained in the
chosen media. Applications are limited to a maximum temperature of 1000°F per
ASME.
Applications
Sulfuric acid pickling
tanks, racks and heating coils
Phosphate coating drums
and racks
Heat exchangers
Bubble caps
Process piping
Mixing tanks
Chemical and petroleum
process equipment
