  • The difference of grade 304 stainless steel and 201 stainless steel
    The difference of grade 304 stainless steel and 201 stainless steel
    304 stainless steel and 201 stainless steel, which are named according to the American AISI standard, are also widely used in many industries,including sanitary ware.  From the appearance,  stainless steels are difficult to distinguish. Both are austenitic stainless steels. Solution-treated 304 and 201 stainless steels are non-magnetic. The magnetic properties are due to internal structure damage caused by cold working or a small amount of ferrite structure. Description of elements composition 304 stainless steel [0Gr18Ni9], 201 stainless steel[1Cr17Mn6Ni5N]. According to GB/T20878-2007 From the element composition table, we can easily find that the nickel content has the largest difference. The level of nickel directly determines the cost, which is why 304 stainless steel is more expensive than 201. It is also the reason why 304 has good corrosion resistance, but 201 is relatively easy to rust. Application in sanitary ware industry NEUNAS linear shower drain made by 304 stainless steel, compare traditional small floor drain, linear shower drain solved the water flow problem esaily. Made by 304 stainless steel, avoide the high cost of using copper, more easy for processing to produce it, at the same time, there is no need to worry about the problem of rust after prolonged use. 304 stainless steel is also used in shower head, shower arm, bathtub faucet, shower enclosure frame, walk-in bathtub door, acrylic bathtub frame, UF toilet seat hinges etc. Spend the necessary expenses to ensure high quality. 201 stainless steell also used in shower head, shower arm, shower faucet tube, bathtub faucet. Reduce quality requirements in order to reduce procurement costs. But usually begin to rust from the inside after about one year of use (depending on the water quality in the area of use) Regarding the problem of rust, I have to say that our 304 stainless steel linear shower drain was once the scapegoat for these rusty faucets. Customers complained that our floor drain was rusted, and suspect that our material is not 304 stainless steel, but the truth is the rust water from those rusty faucets, mixer with shower gel and shampoo stuck to our linear drain. It can be easily removed through a steel ball or a scouring pad, and you will find that our shower drain surface is the same as when you first bought it. One simple example, everyone has seen rusty tiles. Will the tiles rust themselves? of course not. Next time, if another end customer complains that our floor drain is rusty, maybe we should suggest that end customer cut his shower faucet tube or shower head and take a look at first, just kidding! PS: The content we described cannot be an excuse to use 201 stainless steel to produce linear drains in order to reduce costs and obtain high profits. We can find the truth from the actual situation, so we need to take every complaint seriously.
