Baosteel Special Metals Co., Ltd. (Baowu Group)

　In our lives, many of the appliances are made of stainless steel, such as various pots and pans. At present,  China Welded Stainless Steel Tubing  is divided into many types, of which 304 stainless steel and 316 stainless steel is mainly used in our daily life. These two kinds of stainless steel are not the same, but the market is not clear on 304 stainless steel and 316 stainless steel. It is better to have the logo, but the logo is not necessarily true. Some merchants sell 316 stainless steel as 304 stainless steel. Light is not clear with the eyes, teach you 3 methods, simply distinguish 316 stainless steel. SUS 316 Stainless Steel Tube 　　 SUS 304 TB Stainless Steel Pipe  and 316 stainless steel are different. Generally, 316 stainless steel has more Ni and Cr elements than 304 stainless steel. The hardness and oxidation resistance are better than 316 stainless steel. 316 stainless steel is better to use. One point is that the price of 316 stainless steel is more expensive in

After a month and a half of intense work, we finally completed the production of 85 tons of  Duplex 2205 stainless steel pipes . This order is from one of our Austrilia clients,  size: OD33.4mm*WT3.56mm*L6,000mm,  5,360pieces. We have consistently supplied him with more than 800 tons of stainless steel pipes.  We always provide high quality stainless steel pipes and high quality service...

   Seamless Stainless Steel Tube  has strong corrosion resistance and is easy to process into various shapes of steel. It has good welding performance and no tendency to be cold and brittle. Therefore widely used. The stainless steel seamless pipe does not undergo a phase change, wherein the heat treatment is to heat to a high temperature to solidify during the process. The stainless steel seamless tube has a low thermal conductivity, and the thermal conductivity can be increased after rising to a high temperature. Stainless steel seamless pipe heating is based on the solid solution rate of the carbide. The 304 stainless steel carbide takes 3 seconds at 1065 degrees Celsius, 1.5 seconds at 1176 degrees Celsius, and 10 seconds at 1000 degrees Celsius. From this point of view, the higher the heating temperature of the stainless steel seamless pipe, the better. However, the higher the heating temperature, the other defects occur at the same time. Will result in a decrease in tensile st

　 Stainless Steel Pipe Ferritic  is generally nickel-free. The main alloying element is chromium. This steel contains relatively low carbon and often contains ferrite forming elements such as aluminum to ensure that the steel is mainly ferrite. The chromium content is generally between 12% and 30%, and the carbon content is mostly less than 0.12%. Ferritic stainless steel is roughly divided into Cr11%-15%, Cr16%-20% and Cr21-30% according to the chromium content in the steel. In addition to stainless steel and local corrosion resistance, ferritic stainless steel is resistant to chloride. Stress corrosion, pitting corrosion resistance, crevice corrosion resistance and other local corrosion performance are the main features of corrosion resistance of such steel. Ferritic stainless steel has high strength and low cold work hardening tendency. Its thermal conductivity is 130%-150% of austenitic stainless steel, and the coefficient of linear expansion is 60% to 70% of austenitic stainless
