2205 stainless steel pipe description
Stainless Steel Pipe 2205 Stainless Steel Pipe 2205Stainless Steel Seamless Pipe 2205 Stainless Steel Welded Pipe
Standard No. of duplex stainless steel 2205: ASTM A240/A240M-01 duplex stainless steel 2205 alloy is a duplex 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 stress corrosion resistance.
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 affordable than 316 317L. This alloy is particularly suitable for temperatures of - 50 ° F/+600 ° F. This alloy can also be considered for applications beyond this temperature range, but there are some limitations, especially for welded structures.
The chemical composition of 2205 can obtain an ideal microstructure after solution annealing at 1900 °/1922 ° F (1040 °/1080 ° C) 50 α / fifty γ . If the temperature of heat treatment is higher than 2000 ° F, the ferrite composition may be increased. Like other duplex stainless steels, 2205 alloy is susceptible to the precipitation of intermetallic phase. The intermetallic phase precipitates between 1300 ° F and 1800 ° F. At 1600 ° F, the precipitation rate is the fastest. Therefore, we need to test 2205 to ensure that there is no intermetallic phase. Refer to ASTM A 923 for the test.
2205 stainless steel
characteristic:
1. Compared with 316L and 317L austenitic stainless steels, 2205
duplex stainless steel alloy has superior performance in resistance
to pitting corrosion and crack corrosion. It has high corrosion
resistance. Compared with austenite, 2205 duplex stainless steel
has lower thermal expansion coefficient and higher thermal
conductivity.
2. The compressive strength of duplex stainless steel 2205 alloy is
twice that of austenitic stainless steel, and the designer can
reduce its weight compared with 316L and 317L. 2205 alloy is
especially suitable for the temperature range of - 50 ° F/+600 ° F.
It can also be used for lower temperatures under strict
restrictions (especially for welded structures).
2205 stainless steel plate, 2205 stainless steel, duplex stainless
steel 22052205 stainless steel material, which is Swedish stainless
steel brand.
Difference between duplex 2205 stainless steel plate and austenitic
304 stainless steel plate
1) The yield strength is more than twice as high as that of
ordinary austenitic stainless steel, and the
Sufficient plastic toughness. The wall thickness of tanks or
pressure vessels made of duplex stainless steel is 30-50% less than
that of common austenite, which is conducive to reducing costs.
2) It has excellent resistance to stress corrosion cracking. Even
the duplex stainless steel with the lowest alloy content has higher
resistance to stress corrosion cracking than the austenitic
stainless steel, especially in the environment containing chloride
ions. Stress corrosion is an outstanding problem that ordinary
austenitic stainless steel is difficult to solve.
3) The 2205 duplex stainless steel, which is widely used in many
media, has better corrosion resistance than the ordinary 316L
austenitic stainless steel, while the super duplex stainless steel
has extremely high corrosion resistance. In some media, such as
acetic acid and formic acid, it can even replace the high alloy
austenitic stainless steel, or even the corrosion resistant alloy.
4) It has good local corrosion resistance. Compared with austenitic
stainless steel with the same alloy content, its wear resistance
corrosion and fatigue corrosion performance are better than
austenitic stainless steel.
5) The linear expansion coefficient is lower than that of
austenitic stainless steel and close to that of carbon steel. It is
suitable for connecting with carbon steel and has important
engineering significance, such as producing composite plates or
linings.
6) No matter under dynamic or static load conditions, it has higher
energy absorption capacity than austenitic stainless steel, which
has obvious advantages and practical application value for
structural members to cope with sudden accidents such as collision
and explosion.
