316L is a stainless steel grades, that mainly contains Cr, Ni, Mo containing numbers indicate the percentage is probably (not accurate, just about), 316L is the material corresponding U.S. label, sus 316L is the corresponding label in Japan. Our standard grade for 022Cr17Ni12Mo2. (New standard) grade of the old chemical composition 00Cr17Ni14Mo2 Edit this paragraph

 316l 
 S S: ≤ 0.030 P P: ≤ 0.035 Chromium Cr: 16.00 ~ 18.00 Nickel Ni: 10.00 ~ 14.00 Molybdenum Mo: 2.00 ~ 3.00 316L because of its excellent corrosion resistance, corrosion resistance in the chemical industry has a wide range of applications, 316L is also part of 18-8 austenitic stainless steel derivatives, add 2 to 3% of the Mo element. On the basis of the 316L, but also bring about many kinds of steel, such as after adding a small amount of Ti derived 316Ti, after adding a small amount of N derived from 316N, to increase Ni, Mo content derived from 317L. 316L available on the market in accordance with American Standard to most of the production. For cost reasons, the general steel products, Ni content of the limit down by as much as possible. American Standard requirements, 316L and Ni content of 10 to 14% on standard provides that, 316L and Ni content of 12 to 15%. The lowest standard, American standard and Japanese standard in the Ni content of 2% on the difference reflects the price is still quite large, so when customers buy products or need to see the 316L, the product is according to ASTM or JIS standard. The Mo content makes the 316L steel has excellent resistance to pitting corrosion, can be safely used in other halogen-containing Cl-ion environment. 316L is mainly used because of its chemical properties, the surface of 316L steel slightly lower inspection requirements (relative to 304), on the surface of demanding clients to strengthen the surface of the inspection.
