How to distinguish between several kinds of common stainless steel filter specifications of the commonly used method.
, nickel content in about 6% of the 301 stainless steel screen mesh, droplet parts do not produce red in 10 seconds, the electricity for 5 seconds, when we remove the battery after 6 minutes into light brick red.
Second, the different levels of
stainless steel screen mesh and antirust performance each are not identical, the stand or fall of the product is according to the testing materials rust resistance to distinguish different stainless steel screen mesh.
Use a drop method to determination of droplet in the material surface, without power first.
Three, stainless steel filter nickel content in about 1% of the 200 series stainless steel screen mesh, the drops of parts will be in 5 seconds into a dark red.
Four, stainless steel filter most of nickel content in about 8% of the 304 stainless steel screen mesh, drop by the site does not produce red for 10 seconds, the electricity for 5 seconds, when we remove the battery does not change color after 15 minutes.
Five, the nickel content in about 4% of the 202 stainless steel screen mesh, droplet parts will do not produce red in 10 seconds, the electricity for 5 seconds, when we remove the battery after 30 seconds into a brick red.
Six, chromium content in about 11% of the 409 and 410 stainless steel screen mesh, when the drop site in 5 seconds into deep brick red.
Seven, chromium content in about 16% of the 430 stainless steel screen mesh, when the parts do not produce red in 10 seconds, the electricity for 5 seconds, when we remove the battery after 1 second at once into a deep brick red.
Eight, stainless steel filter chromium content in about 21% of the 443 stainless steel screen mesh, when the drop does not produce the red parts of the 10 seconds, the electricity for 5 seconds, when we remove the battery after 15 minutes.
In short to identify stainless steel filter, the main method is to observe the red speed faster material rust resistance, the deeper the color;
Turn red when the better rust resistance speed slower, the lighter color.
As for 13903185162, 200, 300 and 400 series stainless steel filter available magnetic strength to distinguish.
200 series, 300 series stainless steel screen mesh for non-magnetic or weak magnetic, 400 series stainless steel filter show strong magnetic.
