1.What is 316L stainless steel?
316L steel is a grade of stainless steel, which mainly contains chromium, nickel and molybdenum. The number indicates the approximate percentage chemical composition contained, 316L steel is the American designation corresponding to this material, and sus316L is the corresponding Japanese designation. my country's standard grade is 022Cr17Ni12Mo2 (new standard), and the old grade is 00Cr17Ni14Mo2.

4.Corrosion resistance of 316L stainless steel plate
The Mo content of 316l makes this steel with excellent resistance to pitting corrosion and can be safely used in environments containing Cl- and other halogen ions. Because 316L is mainly used for its chemical properties, steel mills have slightly lower requirements for surface inspection of 316l steel (compared to 304), and customers with higher surface requirements should strengthen surface inspection.
5.Production standard of 316L stainless steel plate
Most of the existing 316L on the market are produced according to American Standard. For cost reasons, steel mills generally try to lower the Ni content of their products to the lower limit. 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 minimum standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is quite huge in terms of price. Therefore, customers still need to see clearly when purchasing 316L products, whether the products refer to ASTM or JIS standards.
6.The difference between 316L stainless steel plate and 316 stainless steel plate
What needs to be reminded is that we usually encounter a similar model called 316 stainless steel plate, which are two different types of steel. The difference is that 316L stainless steel plate has lower carbon content than 316 stainless steel plate, and at the same time molybdenum The content of 316 is slightly higher than that of 316. It is this difference that makes 316L stainless steel better than 316 stainless steel in resistance to carbide precipitation, and can be used in the temperature range mentioned above. For those of us who have less exposure to the stainless steel industry, we need to pay attention to this when purchasing 316L stainless steel plate to avoid buying the wrong one. However, in terms of practical use, because the difference in production cost between ordinary 316 stainless steel plate and 316L stainless steel plate is not too large, and the performance of 316L stainless steel plate is significantly better than that of ordinary 316 stainless steel plate, users generally prefer 316L stainless steel plate. From the perspective of producers, it is precisely because consumers buy more 316L that steel mills reduce the production of 316 accordingly. Therefore, almost all we see from the market are low-carbon 316L stainless steel plates.
7.The application of 316L stainless steel plate in life
At present, 316L stainless steel plate has been widely used in food, chemical, medical and other industrial equipment and decoration fields. The carbon content of 316L stainless steel is 0.03, which can be used in applications where annealing cannot be performed after welding and corrosion resistance is required. At the same time, it is also a good material suitable for sheet metal processing. Because of its good gloss, it can achieve very good results after surface treatment, and the appearance is very beautiful. For example, when we sometimes take a high-rise elevator, the surface that feels smooth and flat in the elevator can be used as a mirror. This must be the effect of the 316L material used after polishing and drawing.In addition to being used in places where anti-corrosion requirements are high in daily life, it is more used in the marine industry and industrial air pollution where the air pollution is relatively serious. In addition, it also has good resistance in the consumption process of pulp and paper making. Corrosion effect; According to authoritative data, 316L not only has good heat resistance, but also has good oxidation resistance when used intermittently below 1600 degrees and in continuous use below 700 degrees.
