Corrosion Resistant Alloy 20 Round Steel Nickel-Based Alloy No8020 Polished Rod

Alloy 20 is an iron-based austenitic alloy used for resistance to sulfuric acid corrosion. It exhibits excellent resistance to sulfuric acid corrosion and is very strong against environments containing phosphoric acid, nitric acid, chlorides, chloride stress corrosion cracking, pitting, and crevice corrosion. Therefore, Alloy 20 is also known as a corrosion-resistant alloy. It finds wide application in industries such as chemical, food, pharmaceutical, power generation, and plastics. Alloy 20 is typically used for resistance to pitting, chloride corrosion, and stress corrosion cracking.

Nickel-based alloy Alloy 20 is mainly composed of nickel, chromium, iron, molybdenum, copper and other elements, among which nickel has the highest content, reaching about 60%. In addition, it also contains about 25% chromium and about 10% iron, as well as a small amount of molybdenum and copper and other elements. The addition of these elements makes Alloy 20 have excellent corrosion resistance and high temperature performance.

• Corrosion resistance: Alloy 20 has excellent corrosion resistance, especially to sulfuric acid and other strong acids. It also has good corrosion resistance to many organic acids, chloride ions and alkaline media.
• Resistance to Stress Corrosion Cracking: Alloy 20 exhibits good resistance to stress corrosion cracking in high temperature and corrosive environments, which makes it particularly suitable for equipment in the chemical processing and petroleum industries.
• Mechanical properties: Alloy 20 not only has good corrosion resistance, but also has good mechanical properties, including good strength and tensile resistance, enabling it to maintain structural integrity in high stress environments.
• Machinability: Alloy 20 has better machinability than other high alloy stainless steels and can be processed and manufactured through conventional machining, welding and forming processes, which makes its application range wider.
• Thermal stability: Under high temperature conditions, Alloy 20 can still maintain good structural stability and mechanical properties, which is crucial for equipment that needs to operate for a long time in a high temperature environment.
• Multi-purpose application: Due to its excellent comprehensive performance, Alloy 20 is widely used in chemical processing, food processing, pharmaceuticals, marine engineering and other fields, especially those occasions with extremely high requirements for corrosion resistance, mechanical properties and reliability.

In general, Alloy 20 is widely regarded as a high-performance stainless steel alloy due to its excellent corrosion resistance, resistance to stress corrosion cracking and good mechanical properties. It is suitable for use in various extreme environments and industrial fields with special requirements.
