Corrosion Resistance
Alloy 20 bolts provide good performance in hot sulfuric acid, specifically they offer good resistance to stress-corrosion cracking in boiling sulfuric acid at specific range of 20% to 40% concentration, as well as general sulfuric acid resistance. Alloy 20 offers solid acid protection and will perform better than Duplex or even Monel, but for high temperature and high concentration acids, you may need to look to Inconel or Hastelloy fasteners. In addition, Alloy 20 bolts also show useful resistance to phosphoric acid and nitric acid.
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.
Key Corrosion Resistant Features:
- Good sulfuric acid protection at 20% - 40%
- Decent stress corrosion cracking, pitting and crevice corrosion resistance in chloride
- Resonable general corrosion protection
- Good intergranular corrosion resistance in the as-welded condition
- Chemical and allied industries
- Tanks
- Valves
- Heat exchangers
- Explosives
- Pickling racks
- Food and dye production
- Manufacture of synthetic rubber and plastics
- Pharmaceuticals
- SO2 scrubbers and other severe environments
Carpenter Alloy 20 Temperature
In addition to their corrosion resistance, Alloy 20 bolts also perform well at moderately high temperatures, with the ability to maintain their mechanical strength up to 1000°F.
Nickel Alloy 20 Welding
Alloy 20 bolts are stabilized with Columbium to minimize carbide precipitation during welding. In addition it offers intergranular corrosion resistance in the as-welded condition.
Alloy 20 Cb Applications
• Power plants rely on alloy 20 bolts for flue-gas desulfurization
• Alloy 20 bolts are used to connect heat exchangers, mixing tanks, metal cleaning equipment, pickling tanks and racks, and piping in mid-range corrosive chemcial processing environments.
• Alloy 20 bolts help solve corrosion issues in food and dye production.
• Manufacturers of plastics and synthetic rubber also utilize alloy 20 fasteners.
Carpenter 20 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.
Also known as Carpenter 20 and 20CB-3, Alloy 20 bolts offer users a combination of nickel, chromium, molybdenum, and copper which provides good general corrosion resistance. Alloy 20 bolts are best suited for mid-range corrosion use – better than steel alloys but not at the level of high performance nickel based alloys like Hastelloy C276. Alloy 20 is a nickel alloy that was specifically designed to withstand the harsh environment of hot sulfuric acid but also performs well in a variety of other acids. Alloy 20 bolts are an ideal choice when you don’t need the corrosion resistance power and price-tag of high performance nickel alloys like Hastelloy C276; but you need something that will give you more protection than 316 stainless steel or even a Super Duplex 2507 stainless steel.
