150mm 6000mm Wire Mesh Demister Pad 2205 Duplex Stainless Steel Demister Mat

                      Alloy 2205 duplex stainless steel wire mesh pad Excellent Corrosion Resistance Wire Mesh Demister Pad

The Alloy 2205 duplex stainless steel wire mesh pad is a double stainless steel made of 21% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness, and good overall and local anti-stress corrosion capacity. Features: 1. Double-phase stainless steel 2205 alloy is more superior to 316L and 317L austenitic stainless steel, 2205 alloy is more superior in anti-splitting and fracture corrosion, which has high corrosion resistance, compared to Austenites. Its coefficient of thermal expansion is lower and the thermal conductivity is higher. 2. Double-phase stainless steel 2205 alloy compared to austenite stainless steel, it is twice as compared with 316L and 317L, and designers can reduce their weight. The 2205 alloy is especially suitable for the temperature range of -50 ° F / + 600 ° F, and in the case of strict restrictions (especially for welding structures), it can also be used for lower temperatures. Main ingredients: C ≤ 0.030 mN ≤ 2.00 Si≤1.00 p ≤ 0.030 s ≤ 0.020 CR 22.0 ~ 23.0 Ni 4.5 ~ 6.5 MO3.0 ~ 3.5 N0.14 ~ 0.20 (Austenitic-ferrite)

Alloy 2205 duplex stainless steel wire mesh pad characteristics

The so-called duplex stainless steel is half of the ferrite and the austenites in its solid ferrous tissue, and the general phase content may have to reach 30%.

Due to the characteristics of the Alloy 2205 duplex stainless steel wire mesh pad organization, the DSS has the advantages of ferrite stainless steel and austenite stainless steel by correctly controlling the chemical composition and heat treatment process.

1. Compared with the austenite stainless steel, the advantages of double phase stainless steel are as follows:

(1) Yield intensity is more than one times higher than that of ordinary austenitic stainless steel and has sufficient plastic toughness required for molding. The wall thickness of the storage tank or pressure vessel manufacturing storage tank or pressure vessel is reduced by 30-50%, which is advantageous for reducing costs.

(2) With excellent ability to straighten the rupture, even the lowest amount of bisphase stainless steel is also capable of higher resistance to stress, stainless stress, especially in an environment containing chloride. Stress corrosion is a highlighted problem that ordinary austenitic stainless steel is difficult to solve.

(3) In many media, the most popular 2205 double-phase stainless steel has better corrosion resistance than ordinary 316L austenitic stainless steel, and super double phase stainless steel has extremely high corrosion resistance, and then in some media, such as acetic acid. Formic acid or the like can even replace high alloy austenite stainless steel, and even the corrosion resistance.

(4) Good partial corrosion resistance, compared to austenite stainless steel with a proportional alloy content. Its wear-resistant corrosion and fatigue corrosion properties are superior to Austenitic stainless steel.

(5) Low linear expansion coefficient than the cissto-stainless steel, and carbon steel is close to carbon steel, it has important engineering significance, such as production of composite plates or lining.

(6) Whether it has higher energy absorption capabilities than the austenitic stainless steel, the structural pieces should be obvious, and the two-phase stainless steel advantages is obvious. .

2, compared with the austenite stainless steel, the weakness of the double phase stainless steel is as follows:

(1) The universality and positiveness of the application is not as good as austenite stainless steel, for example, its use temperature must be controlled below 250 degrees Celsius.

(2) It is not as good as austenite stainless steel compared with the austenite stainless steel.

(3) There is a medium-temperature brittle crisp zone, and the process system for heat treatment and welding needs to be strictly controlled to avoid harmful phases, and the performance.
