Nowadays, stainless steel has developed hundreds of grades. According to the classification of stainless steel internal structure, it can be divided into martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, duplex steel and so on.
Here are a few of the stainless steel grades commonly used in chemical production.
304 stainless steel, the most common type of steel, is generally used to make a variety of containers, vacuum flasks, used in the food industry to make equipment, is currently a relatively high-grade civilian steel, belonging to austenitic stainless steel. Coincidentally, a certain mobile phone brand used to use this steel to enhance the fortune. In fact, 304 stainless steel is very common, we generally use it for its own equipment, the price is not expensive, it is 18,000 / ton.
201 stainless steel, a cheap stainless steel, mainly because of the nickel in our country, and 201 steel in the stainless steel mainly replaces nickel with manganese, so the price is cheap. Civilian is mainly used to make some low-end stainless steel products. The price of 201 steel is only about 70% of 304 stainless steel.
316L stainless steel, 304 steel enhanced version, due to the addition of molybdenum, corrosion resistance is significantly improved compared to 304 steel.
2205 stainless steel, also known as 2205 duplex steel, 2205 duplex steel is also widely used in chemical industry, mainly because of its ability to resist chloride ion corrosion. Chloride ion can be said to be a nightmare of stainless steel, because in the presence of chloride ions, it will cause intergranular corrosion of stainless steel that why stainless steel rust, so in the chemical plant to transport chlorine-containing substances, such as salt water, some people prefer carbon steel and stainless steel, but duplex 2205, the corrosion resistance of steel in this respect is very excellent.
310S stainless steel, which is also the best in stainless steel, mainly used in high temperature environment, normal stainless steel use temperature should not exceed 600 degrees, otherwise the internal structure may change, the strength is difficult to guarantee, 310S in the case of more than 600 degrees, corrosion resistance and strength They can all be maintained at a high level, so they are often used in high-temperature environments with certain corrosion, such as various chemical furnaces. Of course, the price of 310S is very touching. It is said that the same pressure-resistant equipment costs more than titanium.
