What is the difference between stainless steel 201 and stainless steel 304?
We often use stainless steel when we make conveyors and other mechanical equipment, as well as material selection for the conveyor chain. Among them, there are two kinds of stainless steel that we often use, stainless steel 201 and stainless steel 304. What is the difference between stainless steel 201 and stainless steel 304?
Chromium content is not the same, the national standard 201 is: 1Cr17Mn6Ni5N, 304 is: 0Cr19Ni9 (0Cr18Ni9).
search for:
Series 200 - Chromium - Nickel - Manganese Austenitic Stainless Steel, Series 300 - Chromium - Nickel Austenitic stainless steel. The meaning of the letters: Cr means chromium Ni means nickel Mn means manganese 1 means carbon content (0 in 304 is not carbon but carbon content is less than 0.1% is low carbon) 201:1Cr17Mn6Ni5N, it means 1% carbon, 17% Manganese, 17% chromium, and 6% nickel austenitic stainless steel 201 stainless steel; 304:0Cr19Ni9 (0Cr18Ni9), representing austenitic stainless steel 304 stainless steel containing less than 0.1% carbon, 18%/19% chromium, and 9% nickel; 201 Stainless steel containing manganese, easy to oxidize in the case of air humidity and salt and heavy maintenance can be easily rusted (of course, the situation is much better than iron products, and stainless steel oxidation rust can be processed for wire drawing, polishing, etc., unlike iron There is no way to handle the corrosion of the electroplated layer on the surface of the product. 304 stainless steel does not contain manganese, chromium and nickel are more, not easy to oxidation and rust; 201 stainless steel price is 3-4 times the price of iron (chrome plated or sprayed furniture), 304 stainless steel is more expensive than 201 stainless steel or nearly 1 times. The 304 surface is shiny white with metal. Relative 201 is like a plastic plate.
The raw materials used are not the same, generally 201 stainless steel with low nickel, 304 nickel content is relatively high; chromium content is different, and 201 relative to 304 acid and corrosion resistance is lower, etc.
