Corrosion Resistant Alloy 20 Round Steel Nickel-Based Alloy No8020
Polished Rod
Alloy 20 Introduction:
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.
Composition of Alloy 20: unit%
Element Name | Cr | Ni | Mo | Cu | C | Si |
Element content | 19.0~21.0 | 32.0~38.0 | 2.0~3.0 | 3.0~4.0 | ≤0.07 | ≤1.0 |
Element Name | Fe | P | Mn | S | Nb | |
Element content | margin | ≤0.025 | ≤2.0 | ≤0.015 | ≤0.5~0.7 | |
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.
Key Benefits of Alloy 20:
- 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.
