Rust corrosion of 316 stainless steel wire mesh refers to its corrosion resistance on the surrounding environment, or is not sensitive to corrosion beginning, subtle passivation.
About many theories are marked 316 passivation of stainless steel wire mesh.
For example, found from the chemical principle, 316 stainless steel wire mesh corrosion resistance.
This is because it exists in the media, film Cr20 as foundation, a kind of passivation film, very thin.
When the chromium content exceed 105%, as long as a few microns.
Film is greater than the proportion of the metal substrate, thin film is very accurate, because the film is very difficult to be corrosive medium penetration, so be careful not corrode metal substrates.
Another such as electronic theory that metal passivation condition associated with the shell of not filling.
In the 316 stainless steel wire mesh and the price of 316 stainless steel wire mesh tube, iron (
Atoms are passivated, because of electronic pole for chrome.
Other scholars thought when titanium alloy of chromium content in solid solution on 1/8 (
One hundred percent)
Electrode potential to add from a 0.
56 v to + 0.
56 v, and electrode potential to add, make the metal in the electrolyte is more secure, that is to say, it is not simple corrosion.
Above all theories are based on the effect of chromium.
In fact, because the set of diversity and complexity, should be added under the condition of must add other alloying elements and strengthen the corrosion function materials, such as molybdenum elements are added, this will make the corrosion product M002 near matrix, progress matrix passivation, and adding copper elements (
Of the 316 stainless steel screen blunt.
Cu0 is contained in membrane, has no effect on the corrosion medium.
Therefore, data add corrosion resistance;
In nitrogen (
The concentration of the elements will be added passivation membrane Cr2N, adding chromium passivation membrane in the concentration, the corrosion resistance of add data.
Demand indicate the corrosion resistance of 316 stainless steel wire mesh is conditional.
Different factors such as varieties of medium, liquid concentration, temperature, pressure, speed and other factors have different effects on corrosion of 316 stainless steel wire mesh.
Therefore, 316 stainless steel stainless steel wire mesh is relative, incomplete and generic.
It is necessary to cause our attention.
