Differences in functionality:
304 is a versatile widely used stainless steel, it is widely used to produce good overall performance (corrosion resistance and formability) of equipment and parts. In buildings can withstand general corrosion, resistant to food processing etching medium (but high temperature concentrated acid and chloride containing components possible corrosion), organic compounds, dyes and wide variety of inorganic compounds can resist.
Type 304L (low carbon), and good resistance to nitric acid, and durable medium temperature and concentration of sulfuric acid, widely used as a liquid gas tank, used for cryogenic equipment (304N), other consumer goods and appliances, kitchen equipment, hospital equipment, transport tools, waste water treatment apparatus.
430 lower than the 304 alloy content, used as a mild atmosphere highly polished decorative purposes, it can also be used nitric acid and food processing equipment.
difference of 201 and 304 stainless steel :
1, Specifications: conventional stainless steel sheet is divided into two models 201 and 304, actually is a component differ, 304 good quality, but the price is expensive, 201 worse. 304 imported Stainless Steel Plate, 201 domestic stainless steel plate.
2, 201 composition of 17Cr-4.5Ni-6Mn-N, the section Ni steel, replace steel 301 steel. After cold working with magnetic, for railway vehicles.
3, 304 composed of 18Cr-9Ni, is the most widely used stainless steel, heat-resistant steel. For food production equipment, past through chemical equipment, nuclear energy.
4, 201 is a high manganese, the surface is very dark with a bright light, high manganese easily rust. 304 chromium containing more matte surface rendering, does not rust. We have put together a comparison of two kinds. The most important thing is different corrosion resistance, corrosion resistance 201 can be poor, so the price will be much cheaper. And because 201 nickel-containing low, the price is lower than 304, so the corrosion resistance as good as the 304.
5, the difference is nickel issues between 201 and 304. And the price is 304 now are more expensive, are generally required to be close to 50,000 a ton, but then at least you can guarantee 304 during use will not rust. (Syrup available to do the experiment)
6, stainless steel because rust is formed on the surface chromium-rich oxide protects the steel body, 201 is a high-manganese steel material hardness of more than 304 high-carbon low nickel.
