304L stainless steel material
At present, there are two kinds of surface raw materials for 304L stainless steel coils we see on the market, one is BA, and the other is 2B. These two surface materials are the most original surface state when the steel factory leaves the factory. Because this 304L stainless steel is the most widely used, coupled with its excellent performance, low price and strong machinability, it is favored by customers and friends. However, the editor of Wuxi Baoneng Stainless Steel wants to remind customers and friends that when choosing and purchasing, the brightness and purity of the surface of 304L stainless steel coil should not be used to judge its quality. For example, the chromium content in the 304L stainless steel coil in the new national standard is 18~20%, and the strength, wear resistance and toughness of the stainless steel are relatively strong. The nickel content in the 304L stainless steel coil is 8~12%, and the increase of the proportion increases the corrosion resistance of the stainless steel. The carbon content of 304L stainless steel coil 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. The price of 304 is low, and in reality, some opportunistic bad manufacturers often pretend to be 304 to promote business consultants in order to obtain high profits.
304 stainless steel, this stainless steel has good corrosion resistance and heat resistance, and the operating temperature is from minus 198° to 800°. It can not only be used in household products, but also widely used in the food industry. A common stainless steel is 316 stainless steel, which is also added with metal molybdenum, which is particularly resistant to atmospheric corrosion and high temperature strength. It can be used in harsh environments and even resist the erosion of sea water. Stainless steel guardrails and stair handrails are such materials, which are also widely used in watches and cameras. Well, strange and unused knowledge has increased.
