2205 (022Cr22Ni5Mo3N)
Material grade: 2205 (022Cr22Ni5Mo3N) dual phase steel
US brand number: UNS31803
German brand: 1.4462
1. Overview of 2205 (022Cr22Ni5Mo3N) dual-phase steel:
The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This feature allows designers to reduce weight when designing products, making this alloy more price advantageous than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range.
Duplex stainless steel 2205 standard number: ASTM A240/A240M--01 Duplex stainless steel 2205 alloy is a composite stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local resistance to stress corrosion. National standards: NAS 329J3L, UNS S32205/S31803, DIN/EN 1.4462, ASTM A240, ASME SA-240;

2205 is a unique duplex stainless steel material with outstanding properties and a wide range of applications. This material is rich in ingredients, mainly composed of elements such as chromium, nickel, molybdenum and nitrogen. Compared with other stainless steel materials, the composite structure of 2205 gives it higher strength, better corrosion resistance and better processing performance.
As an important stainless steel material, 2205 has a wide range of applications. It can be used in the manufacture of high-temperature and high-pressure chemical reactors, pipelines and heat exchangers, as well as various crude oil and natural gas processing equipment. In addition, 2205 can also be used in fields such as building and bridge structures, marine engineering and aerospace fields.
Compared with other stainless steel materials, 2205 has many advantages. First, its dual-phase structure gives it higher strength and better corrosion resistance. Secondly, the composition of 2205 can be adjusted to achieve better mechanical properties and corrosion resistance. In addition, 2205 also has better weldability and processing performance. All these advantages make 2205 the leader among stainless steel materials.
In the United States and Japan, the corresponding grades and standards of 2205 are UNS S31803 and JIS SUS329J3L respectively. These standards are strict and ensure that the quality and performance of 2205 meet international standards.
Overall, 2205 is a duplex stainless steel material with outstanding performance and wide application. Its unique composite structure, excellent mechanical properties and corrosion resistance, and flexible composition adjustment capabilities make it one of the most popular stainless steel materials in many fields.
2205 is a high-strength, corrosion-resistant duplex stainless steel material whose properties are highly sought after in industry. As a representative of new stainless steel materials, 2205 has many unique features and advantages. It is not only guaranteed in terms of quality, but also has good performance in terms of service life and other aspects. This time, we will give an in-depth introduction to the performance, composition, application range, differences and corresponding American and Japanese standards of 2205.
First of all, 2205 shows its excellent advantages in terms of material performance. Compared with other stainless steels, 2205 has higher corrosion resistance and mechanical strength, as well as excellent welding and processing properties. Such characteristics make 2205 widely used in shipbuilding, chemical industry, petroleum and other fields.
Secondly, in terms of composition, the main components of 2205 stainless steel are iron, chromium, nickel, molybdenum and nitrogen. The ratio of these ingredients gives 2205 corrosion resistance and strength that surface-coated stainless steel does not have. At the same time, the nickel content of 2205 is low, which makes its cost relatively low and more economical and practical.
Then, we need to understand the application scope of 2205. This stainless steel material is widely used in shipbuilding, chemical industry, petroleum, natural gas and other fields. Especially in the marine field, 2205 is widely used in the manufacture of equipment such as ships and offshore drilling platforms. It has better corrosion resistance and resistance to seawater erosion in seawater, which can greatly extend the service life of equipment.
Compared with other stainless steels, the advantage of 2205 is its mixed-phase structure. This structure gives 2205 higher mechanical strength and better corrosion resistance than other single-phase stainless steels. At the same time, the cost of 2205 is lower than other stainless steels, so it can better meet the needs of different regions and fields.
The United States and Japan have also formulated corresponding standards and brands respectively. In the United States, the standard for 2205 is ASTM A240, and the grade is UNS S32205. In Japan, the standard for 2205 is JIS G4304, and the brand name is SUS 329J3L.
In general, 2205 is a stainless steel material widely used in the industrial field. It has high mechanical strength, corrosion resistance and economic practicability. In the future development, we believe that 2205 stainless steel material will be used in more fields, bringing more convenience to people's production and life.
