What are the stainless steel stainless steel screen mesh of the part raw material to stainless steel screen mesh
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. Stainless steel 201, and 304 out of ordinary people is difficult to differences from the naked eye, in order to avoid more bad manufacturers continue to blind our vibrating screen users, disrupted the market phase, this will affect the users to use and produce. 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 5 chromium nickel chromium stainless steel 201 is 17 elements also contains six manganese element, is 19 304 10 nickel chromium elements; So will cause them in color, corrosion resistance, acid-proof alkaline, patience and many other differences. From the point of color, stainless steel filters for 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, stainless steel and 304 because they do not contain 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, stainless steel filter experimenting on hard stroke knives, appearance after a stroke in 201 there will be a very significant scratches, 304 appearance doesn't have significant scratches.
