Duplex stainless steel wire mesh A common grades of duplex stainless steel wire mesh and USES?
Duplex stainless steel wire mesh is a special kind of stainless steel wire mesh, is one of the most common brand: 2205 is by 21% chromium, 2.
5% molybdenum and 4.
Nitrogen 5% nickel alloy consisting of duplex stainless steel, it has high strength, good impact toughness and good overall and partial stress corrosion resistance.
2205 duplex stainless steel yield strength is twice that of austenitic stainless steel, this feature enables designers when designing products lose weight, make this alloy is better than 316317 L have price advantage;
This alloy is particularly suited to -
+ 50 ° F / 600 ° F temperature range, the temperature is beyond the scope of application, also can consider this kind of alloy, but there are some limitations.
Especially when applied to the welding structure, 2507 duplex stainless steel is in the second generation developed on the basis of duplex stainless steel 2205, currently has SAF2507, UR52N +, Zeron100, S32750, 00 cr25ni7mo4n brand, such as 2507 group consists of austenite and ferrite, both austenitic stainless steel and ferritic stainless steel dual characteristics.
Austenitic stainless steel is better than a lower thermal expansion coefficient and higher thermal conductivity, the pitting corrosion factor (
More than 40, has the very high resistance to pitting corrosion, clearance corrosion resistance, resistance to chloride stress corrosion cracking performance, at the same time with high strength, high fatigue strength, high toughness at low temperature, etc. , is a kind of widely used duplex stainless steel.
