316L stainless steel 316 stainless steel pipe precision seamless pipe welded pipe manufacturer.
316L is widely used in the chemical industry due to its excellent corrosion resistance. 316L is also a derivative steel of 18-8 austenitic stainless steel, with 2-3% Mo added. Based on 316L, many steel grades are also derived, such as 316Ti derived by adding a small amount of Ti, 316N derived by adding a small amount of N, and 317L derived by increasing the Ni and Mo content.
Most of the existing 316L on the market are produced according to the American standard. For cost considerations, steel mills generally keep the Ni content of the product as low as possible. The American standard stipulates that the Ni content of 316L is 10-14%, while the Japanese standard stipulates that the Ni content of 316L is 12-15%. According to the lowest standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is still quite huge in price, so customers still need to see clearly when purchasing 316L products, whether the product refers to ASTM or JIS standards.
The Mo content of 316L makes this steel have excellent corrosion resistance and can be safely used in environments containing halogen ions such as Cl-. Since 316L is mainly used for its chemical properties, steel mills have slightly lower surface inspection requirements for 316L (relative to 304), and customers with higher surface requirements should strengthen surface inspection efforts.

The two most commonly used stainless steels are 304 and 316 (or 1.4308 and 1.4408 in German/European standards). The main difference between 316 and 304 in chemical composition is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more corrosion-resistant than 304 in high temperature environments. Therefore, in high temperature environments, engineers generally choose 316 parts. But there is no absolute. In a concentrated sulfuric acid environment, no matter how high the temperature is, don't use 316. Otherwise, it will be a big deal. Everyone who studies mechanics has learned about threads. Remember that in order to prevent the threads from biting at high temperatures, a black solid lubricant needs to be applied: molybdenum disulfide (MoS2). From this, two conclusions can be drawn: First, Mo is indeed a high-temperature resistant substance. Second, molybdenum easily reacts with high-valent sulfur ions to form sulfides. Therefore, no stainless steel is super corrosion-resistant. In the final analysis, stainless steel is a piece of steel with more impurities (but these impurities are more corrosion-resistant than steel), and steel can react with other substances.
