ALLOY 20 COIL GENERAL PROPERTIES:

Alloy 20 (UNS N08020) is an austenitic, nickel-iron-chromium based super alloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion. It is also stabilized with Columbium to minimize carbide precipitation during welding. Alloy 20 appears to fall between both the stainless and nickel categories as it contains characteristics of both. It was designed for maximum resistance to acid attack and demonstrates superior resistance to stress-corrosion cracking in boiling 20% to 40% sulfuric acid, and also has excellent general corrosion resistance to sulfuric acid and to chloride stress corrosion cracking. Alloy 20 has good mechanical properties at both ambient and elevated temperatures, up to approximately 930°F (500°C) and is readily fabricated by usual industrial processes.

ALLOY 20 COIL APPLICATIONS:

Alloy 20 was originally designed for use in sulfuric acid related applications; however, it is now frequently used in a wide variety of industries. Applications that commonly use Alloy 20 include:

• Chemical and allied industries
• Food and dye production
• Heat exchangers
• Explosives
• Tanks
• Valves
• Pickling racks
• Manufacture of synthetic rubber and plastics
• Pharmaceuticals
• SO2 scrubbers and other severe environments

ALLOY 20 COIL CORROSION RESISTANCE:

• Excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids.
• Nickel content aids in chloride ion stress and corrosion resistance.
• Additions of Copper and Molybdenum provide resistance to hostile environments, pitting, and crevice corrosion.
• Chromium adds to its resistance of oxidizing environments such as nitric acids.
• Columbium reduces the effects of carbide precipitation.

ALLOY 20 COIL WELDABILITY:

• All commonly used welding methods, with the exception of oxyacetylene, can be successfully used.
• The presence of Columbium tends to minimize the precipitation of carbides in the heat-affected zone, so the material may be used in the as-welded condition in most cases.
• Pre-heating is not required.

ALLOY 20 COIL HEAT TREAMENT:

• Cannot be hardened by heat treatment.
• Stabilized-annealing is done at 1750-1850°F, followed by water quenching.
• Stress relieving can be performed on annealed material up to 950°F.

ALLOY 20 COIL PROCESSING - HOT FORMING:

• Heat uniformly to a starting temperature of 2100-2225°F. Finish forging before the stock drops below 1800°F.
• In order to stabilize the material after hot working operations, reheat at 1750-1850°F for a minimum of 1/2-hour per one inch of thickness and water quench.

ALLOY 20 COIL PROCESSING - COLD FORMING:

• Alloy 20 has good cold formability. Bending, drawing and pressing, and other forming operations that occur in the production of fabricated items are readily performed.
• Alloy 20 can normally be press brake bent over a radius twice the materials thickness.
• After cold reductions of more than 15%, a final stabilizing annealing is often required.

ALLOY 20 COIL MACHINABILITY:

Because of Alloy 20′s high work-hardening rate the following are required:

• Only low surface-cutting speeds are possible compared with low-alloy standard austenitic stainless steel.
• Tools should be engaged at all times.
• Heavy feeds are important in getting below the work-hardened 'skin'.
