There are two kinds of surface materials used for 304L stainless steel coils that we see on the market, one is BA and the other is 2B. These two surface materials are the most original surface states when the steel mill leaves the factory. Because this 304L stainless steel has the widest range of uses, coupled with its excellent performance, low price, strong machinability, etc., it is deeply favored by customers and friends. However, Dashi Jiushin editor would like to remind customers and friends that when choosing to buy, they cannot only judge the quality of 304L stainless steel coils by the brightness and purity of the surface. For example, in the new national standard, the chromium content in 304L stainless steel coils is 18~20%, and the strength, wear resistance and toughness of this stainless steel are relatively strong. The nickel content in 304L stainless steel coils is 8~12%, and the increase in proportion enhances the corrosion resistance of the stainless steel. The carbon content of 304L stainless steel coils is extremely low, less than 0.03%, so 304L stainless steel has the ability to resist intergranular corrosion.
304 stainless steel is one of the most widely used mainstream steels at present, because of its obvious corrosion resistance, while 201 stainless steel has relatively poor corrosion resistance, resulting in different widely used areas and different prices. 201 is cheaper than 304, and in reality, it is often used by some opportunistic bad manufacturers to pretend to be 304 to promote business consultants in order to obtain high profits.
This kind of stainless steel has good corrosion resistance and heat resistance, and the use temperature ranges from minus 198° to 800°. It can be used not only in household products, but also in the food industry. A common stainless steel is 316 stainless steel, which also adds metal molybdenum, and has excellent atmospheric corrosion resistance and high temperature strength. It can be used in harsh environments and can even resist the erosion of seawater. Stainless steel guardrails and stair handrails are made of this material, and are also widely used in watches and cameras. Well, the strange and useless knowledge has increased a little bit.
