Bright Annealed Stainless Steel Tube 316l Seamless Straight

  Stainless steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; Corrosion steel is called acid-resistant steel.Due to the difference in chemical composition of the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive.

  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 price. Therefore, customers still need to see clearly when purchasing 316L products, whether the product refers to ASTM or JIS standards.
