What is the difference between 316 stainless steel punching mesh and 304?
Stainless steel wire mesh is not completely rust-free. The reason why stainless steel is not easy to rust is because its internal composition contains chromium. The surface layer reacts with oxygen to produce a chromium-rich oxide film. This layer of oxide film acts as a gold bell. The function of the cloth shirt, under normal circumstances, this layer of oxide film can prevent oxygen, moisture and metal reaction, protect the internal material from oxygen attack, if the outer layer of chromium-rich oxide film is destroyed, it will repair itself, in oxygen An oxide film is produced underneath to ensure that the interior does not corrode.
The corrosion resistance of stainless steel is relative and it is easy to rust in some specific environments. Stainless steel, like other metals, is oxidized and rusted by hand or under certain acid and alkali substances. Therefore, daily life requires frequent cleaning of stainless steel. Usually, dry cloth can be used to wipe out stains on stainless steel surfaces. It is to stick some talcum powder on the dry cloth, which will make it easier to clean.
The stainless steel products we use are 304 and 316 stainless steel. What is the difference between these two stainless steels? Both 304 and 316 are very common. 304 stainless steel is very sensitive to pitting corrosion. It is easy to rust in some environments. In order to solve this problem, 316 stainless steel has been developed. 316 stainless steel has an additional 2%-3% molybdenum added. Molybdenum reduces susceptibility to pitting corrosion and also reduces corrosion of organic acids.
Molybdenum is relatively scarce, so the price of 316 stainless steel is relatively high. The corrosion resistance of 304 stainless steel and 316 stainless steel is almost the same. Unless the content of chloride ion in the medium is very high, 316 stainless steel is more suitable.
