253MA stainless steel wire mesh product material, characteristics, application industry and features
253MA stainless steel wire mesh type 253MA (S30815) nickel-saving heat-resistant austenitic stainless steel wire woven mesh/woven mesh/screen/round hole screen.
Main components:
C≤0.09 N ≤0.17 Cr ≤21 Ni ≤11 Mo≤ 4.1

Product characteristics: 253MA is a heat-resistant austenitic stainless steel designed for applications requiring high creep strength and good corrosion resistance. Its operating temperature range is 850~1100 ℃.
1. Compared with 310S and 1Cr20Ni14Si2, it has better performance, saves Ni and is cheap.
2. It has high strength at 900 ℃. In air, it can be used up to 1150 ℃ under non-pressure conditions and has excellent high temperature oxidation resistance.
3. The short-term tensile strength at each temperature is more than 20% higher than that of ordinary stainless steel (such as 304, 310S).
4. It has high temperature and long-term performance (creep performance, durability).

253MA use: In addition to the alloying elements chromium and nickel, this grade of stainless steel also contains a small amount of rare earth metals (REM), which significantly improves its oxidation resistance. Nitrogen is added to improve creep properties and make this steel completely austenitic. Although the chromium and nickel content is relatively low, this stainless steel has the same high-temperature properties as highly alloyed alloy steels and nickel-based alloys in many cases.

253MA application areas:
1. It can be used in metallurgy, petrochemicals, energy and power and other fields.
2. It is widely used in the production of the cyclone separator center tube of environmentally friendly circulating fluidized bed boilers.

What are the application areas of 254smo stainless steel?
Application areas:
1. Marine: marine structures in marine environments, seawater desalination, seawater aquaculture, seawater heat exchange, etc.
2. Environmental protection field: flue gas desulfurization equipment for thermal power generation, wastewater treatment, etc.
3. Energy field: atomic power generation, comprehensive utilization of coal, tidal power generation, etc.
4. Petrochemical field: oil refining, chemical and chemical equipment, etc.
5. Food field: salt making, soy sauce brewing, etc.
6. High concentration of chloride ion environment: papermaking industry, various bleaching devices
 
The corrosion resistance of 254SMO stainless steel mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and internal organizational structure, and the main role is played by chromium. Chromium has high chemical stability and can form a passivation film on the surface of steel, isolating the metal from the outside world, protecting the steel plate from oxidation, and increasing the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases. The total chemical element content of 254SMO stainless steel is Cr: 19.5~20.5, and the content of this element lays a good foundation for the corrosion resistance of 254SMO stainless steel.
