316 stainless steel angles :

316L is widely used in the chemical industry due to its excellent corrosion resistance. 316L is also a derivative steel of 18-8 type austenitic stainless steel, with 2 to 3% Mo element added. On the basis of 316L, many steel grades are also derived. For example, 316Ti is derived from adding a small amount of Ti, 316N is derived from adding a small amount of N, and 317L is derived from increasing the content of Ni and Mo.

Most of the existing 316L on the market is produced in accordance with American standards. For cost considerations, steel mills generally keep the Ni content of their products as low as possible. The American standard stipulates that the Ni content of 316L is 10-14%, and the Japanese standard stipulates that the Ni content of 316L is 12-15%. According to the minimum standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is still quite huge in terms of price. Therefore, customers still need to see clearly when purchasing 316L products, whether the product is based on ASTM or JIS standards.

321 Stainless Steel Angles :

 to resistance to oxidizing acid media corrosion, this type of steel can also be resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu. If the carbon content in this type of steel is less than 0.03% or contains Ti and Ni, its resistance to intergranular corrosion can be significantly improved. High-silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid. As austenitic stainless steel has comprehensive and good comprehensive properties, it has been widely used in various industries.

321 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in petrochemical, electric power, bridge and automobile industries [1]. However, the "stainlessness" of stainless steel is not absolute. Due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature will have a greater impact on the corrosion resistance of stainless steel. For example, if used for a long time within the sensitization temperature range of 450~850℃, stainless steel will undergo intergranular corrosion. The mechanism is that C combines with Cr at the grain boundary to form Cr23C6 and precipitate, which reduces the Cr content at the grain boundary. This is the so-called "chromium depletion". The Cr element is one of the main elements that inhibit intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.

409L stainless steel has excellent corrosion resistance and is suitable for prolonging the life of automobiles and reducing the weight of automobiles. As an environmentally friendly material that can be recycled and reused, major automobile manufacturers such as GM, Ford, Volkswagen, DaimlerChrysler and other major automobile manufacturers use stainless steel in their exhaust systems. . The automobile exhaust system treats the high-temperature, high-speed combustion exhaust gas generated by the automobile engine and discharges it to the outside of the automobile. The main function of the exhaust system is to reduce vibration and noise, and after reburning the exhaust gas, it is converted into clean gas. Automobile exhaust system is the longest part of automobile components. The system has to withstand extreme temperature changes (-20～850℃) and high-frequency vibration of high-temperature and high-speed exhaust gas, and it is in the car with the largest changes and the most complex In the environment, the temperature limit that 409L can withstand is (-20～650℃).

Due to the increasingly stringent environmental protection standards for automobile exhaust, the increase in short-distance urban driving, and the spread of snow removal agents in winter, the exhaust system usage standards have also become increasingly strict. From the European II-Euro IV standards, traditional steel materials cannot meet the requirements. Technical requirements, high-end motorcycle exhaust system has adopted 409L material. The amount of 409L stainless steel used in each vehicle is 35KGS-65KGS.
