Introduction

Standard: ASTM A240 / A240M- 01 Duplex stainless steel 2205 alloy is duplex stainless steel consisting of 22% chromium, 2.5% nitrogen and 4.5% molybdenum nickel alloy . It has high strength, good impact toughness and good stress corrosion resistance of global and local . The yield strength of 2205 duplex stainless steel is twice that of austenitic stainless steel, this feature makes the designer can lose weight when designing products , make this alloy have an advantage compare with316,317Lin price. This alloy is particularly suited to - + 50 ° F / 600 ° F temperature range. Beyond the temperature range, also can consider this kind of alloy, but there are some limitations, especially when applied to the welding structure.

ApplicationRange

·Pressure vessels, tanks, high pressure pipes, heat exchangers, chemical processing industry).

·Oil and gas pipelines, heat exchanger fittings.

·Sewage treatment system

·Pulp and paper industry classifier and bleaching equipment, storage processing system.

·High strength of rotating shaft corrosion environment, squeezing rollers, blades, impeller, etc.

·Cargo box of a ship or truck

·food processing equipment

Corrosion Resistance

Uniform Corrosion

Because of the content of chrome , molybdenum and nitrogen is 22% ,3% and 0.18%, the corrosion resistant of2205 inmost of the environment is better than316Land317L.

Local corrosion

Due to the content ofchromium, molybdenum and nitrogen , 2205 duplex stainless steel, has a strong corrosion resistance to the pitting corrosion and crack corrosionin the oxidation and acid solution.

Resistance to stress corrosion

Duplex microstructure of Stainless steel is helpful to improve the ability of the resistance to stress corrosion cracking . In a presence of certain temperature, oxygen tension, and the chloride, chloride stress corrosion will happen on austenitic stainless steel. Because of these conditions is not easy to control, the use of304 l,316 land317 lis limited in this respect.

Corrosion fatigue

Thehigh strength and corrosion resistance of dual phase steel 2205, make it has high resistance to corrosion fatigue strength. Processing equipment susceptible to corrosion environment and the influence of the loading cycle, the 2205 is very suitable for such applications.

Structure

The chemical composition of 2205 after a 1900 ° 1900 ° F (1040 ° or 1080 ° C) solid annealing treatment, can obtain ideal microstructure 50 alpha / 50 gamma. If the heat treatment temperature higher than 2000 ° F, may result in ferritic components increase. Like the rest of the duplex stainless steel, alloy 2205 is easy affected by intermetallic phase precipitation. Intermetallic phase between 1300 ° and 1800 ° F precipitation, under temperature of 1600 ° F, the precipitation speed is the fastest. Therefore, we need to test 2205, ensure no intermetallic phase, test refer to ASTM A 923.

Features

1.Compared with 316 L and317Laustenitic stainless steel, 2205 alloy have a superior performance in the resistance to pitting corrosion and crevice corrosion.Compared with the austenitic,it has lower thermal expansion coefficient, so thermal conductivity is higher.

2.The compressive strength duplex stainless steel 2205 alloy is two times of austenitic stainless steel, compared with 316Land317L, the designer can reduce the weight. The temperature range + 50 ° F / 600 ° F , is especially suitable for 2205 alloy , under the condition of the strictly limited (especially for welding structure), can also be used to the lower temperature.
