What is Alloy 20 Stud Bolt?
Alloy 20 Stud Bolt is a nickel-chromium-molybdenum stainless steel that resists pitting corrosion and chloride ion stress corrosion cracking. It is a commonly used alloy in the chemical, food, pharmaceutical & plastics industries.
UNS N08020 Stud Bolt is a high-strength, medium corrosion resistance alloy that can be forged & cold-formed by all standard processes. Alloy 20 Stud Bolts are typically found in the chemical, petroleum & petrochemical industries and in the processing of heavy chemicals and plastics. They are also used in heat exchangers, mixing tanks, & process piping.
Alloy 20 is a good option for those looking for an alloy that offers more corrosion resistance than 316 stainless steel or Super Duplex 2507 stainless steel, but without the price tag of these higher-performance nickel alloys. It also has a higher copper content than chromium which helps to protect it from sulfuric acid. This makes it a great choice for applications where it is necessary to work in corrosive environments. For example, Alloy 20 can be used in flue gas desulfurization systems where oxidation & chloride stress corrosion cracking may occur with other stainless steels.
Benefits of Alloy 20 Stud Bolt
Alloy 20 Stud Bolt is made from a nickel-chromium alloy. The alloy contains 32.5% nickel, 19% chromium & other elements such as carbon, copper, molybdenum, manganese, silicon, and columbium.
It is a durable alloy that can withstand various concentrations of sulfuric acid. It is also known for its resistance to corrosion cracking. This alloy is commonly used to produce explosives, chemicals, and plastics.
The alloy’s low carbon content helps it resist sensitization and carbide precipitation during welding, which increases its corrosion resistance. It is also a cost-effective alternative to other nickel-based alloys.
This alloy has a low-temperature coefficient of expansion, which prevents distortion and cracking during heating and cooling cycles. It is also easy to form and machine.
It is a durable, corrosion-resistant alloy that can withstand many types of chemicals and temperatures. It is also an excellent choice for applications that require resistance to chloride stress corrosion cracking. It is also resistant to seawater corrosion. This alloy is available in many forms, including sheets, plates, bars, and pipe tubes. It can be cold-worked or hot-worked.
Uses of Alloy 20 Stud Bolt
Alloy 20 Stud Bolts are used in applications that demand high performance, such as chemical processing equipment, valves & flanges in petrochemical plants, and desalination systems. They offer increased wear resistance, good formability, and ductility. They also resist stress corrosion cracking, pitting, and crevice corrosion.
As austenitic stainless steel, Alloy 20 has a wide range of uses and is popular for its excellent corrosion resistance in corrosive environments. It is especially suited to sulfuric acid and other corrosive liquids.
The alloy is a good choice for applications requiring oxidation resistance and can withstand service temperatures up to 925 Degrees C. It is also resistant to chloride stress corrosion cracking, allowing it to be used in a variety of applications.
The alloy is also able to be welded with minimal carbide precipitation, thanks to its inclusion of columbium. Its oxidation resistance is similar to that of grade 316. Alloy 20 is widely accepted for use in a wide range of industries, including the chemical, petroleum, and petrochemical industries, as well as paper and pulp plants.
