Is there any difference between 316L and 316 stainless steel? Is it better to make 316L stainless st

1.In terms of chemical composition, 316L stainless steel has a lower carbon content than 316 stainless steel. The details are as follows.

Table 1: Chemical Composition of Stainless Steel %

Grade C Si Mn P S

0cr18ni9(sus 304) ≤

00cr19ni10(sus 304l) ≤

0cr17ni12mo2(sus 316) ≤

00cr17ni14mo2(sus 316l) ≤

Grade: NI CR MO

0cr18ni9(sus 304) -

00cr19ni10(sus 304l) -

0cr17ni12mo2(sus 316)

00cr17ni14mo2(sus 316l)

It can be said that "316L" is ultra-low-carbon 316 stainless steel.

2.In terms of strength, 316 stainless steel has greater tensile strength than 316L stainless steel. The tensile strength of 316 stainless steel is required to be greater than 520MPa, and the tensile strength of 316L stainless steel is only required to be greater than 480MPa

This is because carbon(c) is a strong austenite-forming element that significantly increases the strength of steel.

3.Carbon has a detrimental effect on corrosion resistance. Especially for stainless steel that needs to be welded, the corrosion resistance of low-carbon 316L stainless steel is not as great as that of 316 stainless steel after welding.

In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be solution annealed after welding. If 316L stainless steel is used, post-weld solution annealing is not required.

4.In terms of production cost, the production cost of 316 stainless steel is slightly lower than that of 316L stainless steel, but the difference is not too big.

5.In terms of actual use, because the difference in production cost between ordinary 316 stainless steel and 316L stainless steel is not too large, and the corrosion resistance and weldability of 316L stainless steel are significantly better than that of ordinary 316 stainless steel, users generally prefer 316L stainless steel. From the producer's point of view, due to the small demand for ordinary 316 stainless steel, steel mills are reluctant to produce.

Therefore, the actual circulation in the market is basically low-carbon 316L stainless steel, and ordinary 316 stainless steel is basically not sold in the market.

Stainless steel water pipes have strong corrosion resistance and can be used in places where 304 stainless steel water pipes are not suitable (such as the seaside). Due to the reasons in Article 5 above, it is not recommended to use ordinary 316 stainless steel for water pipes.

7.For most occasions, 304 stainless steel water pipes can meet the requirements of use. 316L stainless steel water pipe due to the high cost, (from the perspective of raw material cost, the ** of 316L stainless steel water pipe is about twice that of 304 stainless steel water pipe.)

Very few people use it. Customization is generally required.

The difference between 316L and 316 stainless steel is that 316L stainless steel has a lower carbon content than 316 stainless steel. 316L stainless steel stainless steel water pipe is mainly due to high anti-corrosion performance and high cost.

If there are no other requirements, 304 stainless steel water pipe is superior in cost over 316L stainless steel.

1.Yield strength: 316 210(n mm2) ; 316l 180(n/mm2)

2.Tensile strength: 316 520 (n mm2); 316l 480(n/mm2)

In short, the biggest difference in use is 316L ultra-low-carbon, L stands for low-carbon, which is low-carbon. Therefore, 316 stainless steel is harder than 316L, but the welding performance and processing performance are poorer. 316L** is generally more expensive than 316.

l Stainless steel, what is the difference between them? Today is a long time to see.

The difference between 316 and 316L: There are the following 2 points.

1.Grade differences.

316 grade 06C17N12M2 (new grade) is equivalent to: American Standard TP316, Japanese Standard SUS316, simply put, 316 material.

316L grade 022C17N12M2 (new grade) is equivalent to: American Standard TP316L, Japanese Standard SUS316L, simply put, 316L material.

To put it simply, the above is the difference between 316 and 316L.

To put it more simply, the biggest difference in use is the 316L ultra-low carbon.

Therefore, when welding, 316L carbon is not easy to precipitate and combine with chromium carbide to form chromium carbide, which can reduce the corrosion phenomenon of the welded part.

If my answer meets your needs, please give us a cause! Thank you.

Summary. Hello, 316L is better. 316 and 316L stainless steels (see below for the properties of 316L stainless steels) are molybdenum-containing stainless steel grades.

The molybdenum content in 316L stainless steel is slightly higher than that in 316 stainless steel. Due to the molybdenum in the steel, the overall properties of this steel grade are better than those of 310 and 304 stainless steels, and under high temperature conditions, when the concentration of sulfuric acid is below 15 and above 85, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride attack properties, so it is commonly used in marine environments.

The maximum carbon content of 316L stainless steel can be used in applications that cannot be annealed after welding and where maximum corrosion resistance is required.

The difference between 316L and 316 stainless steel, which is better.

Stainless steel has better resistance to carbide precipitation than 316 stainless steel.

2.The welding manufacturability of 316L is better than that of 316.

The difference between 316L and 316 stainless steel, which is better.

Hello dear, I am a master of home problem solving, and I am happy to answer for you. The difference between 316L and 316 stainless steel, which is better The question you asked, I am as follows. First of all, there is a difference in composition, 316L is ultra-low-carbon, L stands for low-carbon, so the carbon content of 316L material is lower than that of 316 material.

Secondly, the corrosion resistance is different, and the 316L stainless steel has better grain boundary corrosion resistance and better anti-corrosion and rust resistance. The strength of the two materials is also different, and the strength of 316L material is lower than that of 316, which is convenient for processing. In addition, the welded section of 316 stainless steel needs to be annealed after welding, while 316L stainless steel does not.

The differences between stainless steel 316 and 316L are as follows:

The molybdenum content in stainless steel is slightly higher than that of 316 stainless steel.

The upper limit of C content is 316L, and the higher the C content, the more likely it is to cause intergranular corrosion. Shanghai Xiangqia metal team, looking forward to your consultation!

The lower limits of tensile strength and yield strength are MPa, respectively, and the lower limits of tensile strength and yield strength of 316L are 485 and 170MPa, respectively.

4. Heat resistance. In the range of 800-1575 degrees, it is best not to act 316 stainless steel continuously, but when 316 stainless steel is used continuously outside of this temperature range, the stainless steel has good heat resistance. The resistance of 316L stainless steel to carbide precipitation is better than that of 316 stainless steel.

5. Heat treatment. Annealing is carried out in the temperature range of 1850-2050 degrees, followed by rapid annealing, followed by rapid cooling. 316 stainless steel cannot be overheated for hardening.

6. Welding. 316 stainless steel has good welding properties and can be welded using all standard welding methods. For optimal corrosion resistance, the welded sections of 316 stainless steel need to be annealed after welding.

If 316L stainless steel is used, post-weld annealing is not required.

l Stainless steel, what is the difference between them? Today is a long time to see.

Hello, 316L stainless steel and 316 stainless steel are similar in chemical structure, and also contain molybdenum, so the performance characteristics are similar, that is, excellent corrosion resistance, atmospheric corrosion resistance, good high temperature strength, can be used under harsh conditions, and excellent non-magnetic work hardening.

The main difference between the two is that 316L stainless steel is a low-carbon steel grade with excellent resistance to intergranular corrosion, so it is suitable for products with special requirements for anti-intergranular corrosion.

Hope it can help you, thank you.

First, the nature is different.

L:316L is a stainless steel grade, AISI 316L is the corresponding American marking, and SUS 316L is the corresponding Japanese marking. China's unified digital code is S31603, the standard grade is 022Cr17Ni12Mo2 (new standard), and the old grade is 00Cr17Ni14Mo2, which indicates that it mainly contains Cr, Ni, and Mo, and the number indicates the approximate percentage.

Stainless steel: 316 stainless steel is an austenitic stainless steel, due to the addition of MO elements, its corrosion resistance and high temperature strength have been greatly improved, and the high temperature resistance can reach 1200-1300 degrees, which can be used under harsh conditions.

Second, the characteristics are different.

L: 316L has a wide range of applications in the chemical industry because of its excellent corrosion resistance, and 316L is also a derivative steel grade of 18-8 type austenitic stainless steel, with the addition of 2 3% MO element. On the basis of 316L, many steel grades are also derived, such as 316Ti is derived after adding a small amount of Ti, 316N is derived by adding a small amount of N hind limb Li, and 317L is derived by increasing Ni and Mo content.

Stainless steel: The corrosion resistance is better than that of 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper. And 316 stainless steel is also resistant to the erosion of the ocean and the aggressive industrial atmosphere.

The difference between 304 and 316 stainless steel pipes.

They are very similar in appearance. SS304%SS316 are austenitic, non-magnetic and non-thermohardenable.

1.The elemental composition is different.

SS304 - Chromium - 18%, Nickel 8%.

SS316 - Chromium - 16%, Nickel 10% and Molybdenum 2% 2Performance is different.

The addition of molybdenum to SS316 helps to resist chlorides such as seawater. More suitable for coastal cities.

SS304 is usually cheaper and is mainly used for kitchen utensils and chain pots, storage tanks.

SS316 has high corrosion resistance and can be used in oil refining equipment, pharmaceutical equipment, fasteners, bolts, etc.

3.The maintenance method is different.

304 stainless steel: good corrosion resistance, oxidation resistance and processability, strong oxidizing acid resistance, stamping, can be used to make containers, tableware, metal furniture, building decoration, and medical appliances. 316 Stainless Steel:

It is more common in seaside buildings, ships, nuclear power chemicals and food equipment, etc., which not only improves the corrosion resistance of chemicals hydrochloric acid and ocean, but also improves the corrosion resistance of brine brine and statesun solution.

4.Grades are different.

The 304 stainless steel grade is 0Cr18Ni9, while the 316 stainless steel grade is 0Cr17Ni12Mo2
