Does the stainless steel plate have 300 material?
200 series stainless steel and 300 series stainless steel, on the surface, even if the experts are also difficult to distinguish. At present, some enterprises are using stainless steel water tank and many users can not identify the authenticity, in the water tank of all or part of the 200 series 304 series as shoddy sales, defrauding the high profits, losses and incalculable risks to the user, the regular brand enterprise market hindered water tank.
In the current nickel price level, the price of 200 series stainless steel nickel content is very low only about half of the 300 series stainless steel, corrosion resistance and toughness in the performance is far less than 300 series stainless steel, only suitable for kitchenware, food processing and other fields, if used in the fields of construction, medical equipment and so on, there will be a lot of hidden danger. 200 series of products containing about 1% nickel can not withstand general atmospheric corrosion.
The stainless steel plate 300 represents a series, including several 301.303.304.321.316L.309S.310S materials.In addition, the classification of stainless steel materials are: Austenitic 200 Series: 201.202 material, austenitic 300 series: 301.303.304.321.316L.309S.310S material, ferrite 400 series: 409.410.420.430.444.443 material.
