Stainless steel screen mesh of the raw material should be choose the material of SUS304.
But there are many bad manufacturers to reduce costs in 201 stainless steel material to replace the 304 stainless steel.
201 and 304 is it very difficult to difference from the ordinary people from the naked eye, in order to avoid more bad manufacturers continue to cover our vibrating screen user, disrupted market phase, this will affect the users to use and produce.
Stainless steel screen mesh of the part raw material is what?
The chemical formula which best characterizes the part raw material: 201 is 1 cr17mn6ni5, 304 is the chemical formula of 06 cr19ni10;
Nickel chromium element, is the primary difference between them is 17 201 chromium nickel chromium element contains 5 6 manganese element, is 19 304 10 nickel chromium elements;
So have them in color, corrosion resistance, acid-proof alkaline, patience and many other differences.
From the point of color, because 201 stainless steel containing manganese element will be more than 304 dark colour, and take some white 304.
In corrosion resistance, because 201 contain manganese element, long-term humid in high salinity environment may rust, and 304 for not containing manganese element, so will not rust.
In acid and alkaline, 201 because the content of nickel element is small, not 304 good acid and alkali resistant function.
304, in patience, patience is better, 201 than 304 hard brittle, experimenting on solid cross knife, appearance after a stroke in 201 there will be a very significant scratches, 304 appearance doesn't have significant scratches.
