UNSS32750 (also known as 2507) duplex stainless steel mesh is a
high-molybdenum and high-chromium alloy mesh. It is highly
resistant to chloride ions, chloride mineral acids, diluted
hydrochloric acid, sulfuric acid, etc.
Corrosion, stress corrosion and other capabilities are also very
strong, so it is mainly used in the marine environment, high
chloride environment, chemical industry and marine marine
filtration system (various valve cartridges, filter cartridges,
filters), due to the difficulty of wire drawing this material, The
smallest wire diameter in China is 0.05 mm, and the maximum mesh
size can be 200 mesh. It can also be customized with high mesh and
thick mesh. The duplex stainless steel wire produced by our
factory.
The network supports chemical testing, and can provide formal
material list, product qualification certificate, portable
spectrometer component detection data, please consult online
customer service for details, thank you for your cooperation!
Main ingredients:
25Cr-7Ni-4Mo-0.27N 22Cr-5.3Ni-3.2Mo-0.16N
National standards:
ASTM/ASME: A240 - UNS S32750 EURONORM: 1.4410 - X2 Cr Ni MoN 25.7.4
AFNOR: Z3 CN 25.06 Az DIN/EN 1.4410, ASME SA-240
Corrosion resistance
General corrosion
The higher chromium and molybdenum content of SAF 2507 gives it a
strong resistance to organic corrosion to organic acids such as
formic acid, acetic acid, etc. SAF 2507 alloys for inorganic acids,
especially those containing chlorides
Inorganic acids also have strong corrosion resistance.
Compared with 904L, SAF2507 has stronger corrosion resistance to
diluted sulfuric acid mixed with chloride ions. 904L is an
austenitic alloy designed to resist pure sulfuric acid corrosion.
316L grade can not be used in hydrochloric acid environment, it may
be subject to local corrosion or overall corrosion. SAF2507 can be
used in diluted hydrochloric acid environment, with strong
resistance to plaque damage and crevice corrosion resistance.
2. Intergranular corrosion
The lower carbon content of nSAF 2507 greatly reduces the risk of
carbide precipitation in the intergranular heat treatment.
Therefore, this alloy has a strong resistance to carbide-related
intergranular corrosion.
3. Stress corrosion cracking
The duplex structure of SAF 2507 gives it a strong resistance to
stress corrosion cracking. Due to its high alloy content, SAF 2507
has better corrosion resistance and strength than 2205.
Cracks are almost inevitable in terms of construction, etc., which
makes stainless steel more susceptible to corrosion in chloride
environments. SAF 2507 has a strong resistance to crack corrosion.
SAF 2507 is included.
The isocratic curve in sulfuric acid with 2000 ppm chloride ion is
0.1 mm/year; the isocratic curve in hydrochloric acid is 0.1
mm/year.
