Anonymous users2024-02-05304L belongs to the American standard austenitic stainless steel.
Executive standard: ASTM A276 A276M-2017
304L is a 304 stainless steel with a lower carbon content.
for applications where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone close to the weld, which can lead to intergranular corrosion of stainless steels in certain environments.
weld erosion).
304L stainless steel.
The chemical composition is shown below:
316L belongs to the American standard austenitic stainless steel, and the implementation standard: ASTM A276 A276M-2017
316L stainless steel.
It is commonly used in pulp and paper equipment, heat exchangers, dyeing equipment, film processing equipment, pipes, materials for the exterior of buildings in coastal areas, and bracelets and cases for high-end watches. Equipment, chemicals, dyes, papermaking, oxalic acid in seawater.
fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.

Anonymous users2024-02-04304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability).
304L is a variant of 304 stainless steel with a lower carbon content and is used in applications where welding is required.
316: After 304, the second most widely used steel grade, mainly used in the food industry, the pharmaceutical industry and surgical equipment, the addition of molybdenum to obtain a special structure that resists corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel".
316L has a wide range of applications in the chemical industry due to its excellent corrosion resistance, and 316L is also a derivative steel grade belonging to type 18-8 austenitic stainless steel, with the addition of 2 3% MO element. It is suitable for welding and has a lower carbon content than 316.

Anonymous users2024-02-03316 and 316L stainless steel have different chemical compositions, corrosion resistance, heat resistance, strength, and welding methods, and the specific differences between the two are as follows
1. Chemical composition
316L stainless steel has a lower carbon content than 316 stainless steel. It can be said that "316L" is ultra-low-carbon 316 stainless steel. 316L stainless steel has a higher molybdenum content than 316.
2. Corrosion resistance
316L stainless steel is more resistant to corrosion.
3. Strength
316 mechanical properties are stronger, 316 stainless steel pipe is greater than 316L stainless steel pipe, 316 stainless steel tensile strength is required to be greater than 520MPa, 316L stainless steel tensile strength is only required to be greater than 480MPaThis is because carbon(c) is a strong austenite-forming element that significantly increases the strength of steel.
4. High temperature resistance
316L stainless steel lasts at high temperatures, while 316 cannot. In the range of 800 1575 degrees, it is better not to act continuously on 316 stainless steel. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel and can be used continuously in the range of 800 1575 degrees.
5. Welding
316 stainless steel has good weldability, and it can be welded by general standard welding methods. The welded section of 316 stainless steel needs to be annealed after welding to improve its corrosion resistance. However, if 316L stainless steel is used, there is no need for post-weld annealing.

Anonymous users2024-02-02The differences between 316L and 316 are as follows:
1. The ingredients are different
From the composition of the composition, it can be clearly seen that the carbon content of 316L is lower, in fact, L is the English low, which stands for low carbon. In addition, the chromium-nickel content of the two is different, and the molybdenum content of the brother slag in the 16L material is slightly higher than that of the 316 material.
2. There are differences in grades
316 grade, the old grade is 0Cr17Ni12Mo2, the new grade is 06C17N12M2, that is, the American Standard TP316, the Japanese standard grade, the old brand is 00Cr17Ni14Mo2, the grade is 022C17N12M2, that is, the standard TP316L, the Japanese Standard SUS316L.
3. There is a difference in strength
The strength of 316L material is lower than that of 316 material, which is convenient for processing.
4. The corrosion resistance of the envy is different
316L stainless steel has better grain boundary corrosion resistance, better corrosion and rust resistance, and excellent lead deficiency and lead deficiency.
5. Heat resistance
316 material can be used intermittently below 1600 degrees, in continuous use below 1700 degrees, but it is best not to use 316 stainless steel in the range of 800-1575 degrees.
6. Different welding methods
The welded section of 316 stainless steel needs to be annealed after welding, while 316L stainless steel does not. 316L carbon is not easy to precipitate and combine with chromium to form chromium carbide, which can reduce the corrosion phenomenon of the welded part.

Anonymous users2024-02-011. The chemical composition is different: 304 is cover stainless steel, its material composition is 0Cr18Ni9, 316L is austenitic stainless steel, and the material composition is 00Cr12Mo2Ti.
2. Different performance: 304 steel grade can resist sulfuric acid, phosphoric acid, formic acid, urea and other corrosion, and is suitable for water, control of gas, wine, milk, CIP cleaning liquid and other occasions with low corrosiveness or no contact with materials. 316L steel grade adds molybdenum on the basis of 304, which can significantly improve its resistance to intergranular corrosion, oxide stress corrosion and reduce the tendency of hot cracking during welding, and it also has good resistance to chloride corrosion.
3. **Different: 316 stainless steel is about twice as large as 304.
