SUS is a Japanese material standard, and 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to 0cr19ni9 in our country

0Cr18Ni9).

Japan also uses the American name as SUS304

He is the Japanese standard name, which is what we often call 304, and the national standard name is 0cr18ni9

SUS304 belongs to austenitic stainless heat-resistant steel, with good corrosion resistance and welding performance, and good thermal strength.

SUS304 corresponds to the domestic grade: 07CR19NI10

SUS304 belongs to the Japanese standard austenitic stainless steel, and the implementation standard: JIS G4303-2005

SUS304 has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, no magnetism and other characteristics.

The chemical composition of SUS304 is shown in the following figure:

From the perspective of chemical composition, SUS304 corresponds to the domestic grade: 0Cr18Ni9

The carbon content of the two is different, and 316L has a lower carbon content and better corrosion resistance. The "L" here means low, and the carbon content is lower. As a low-carbon series of 316 steel grades, in addition to having the same characteristics as 316 steel, 316L has excellent resistance to grain boundary corrosion.

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.

SUS316 refers to 316 stainless steel. SUS is a Japanese material standard, and 316 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. There is no difference in essence.

316ss is a molybdenum-containing stainless steel grade. The total performance of this steel grade is better than that of 310 and 304 stainless steel, under high temperature conditions, when the concentration of sulfuric acid is lower than 15 and higher than 85, the material composition of 316Ss stainless steel, the material composition of the group: C maximum, Mn maximum, P maximum, S maximum, Si maximum, Cr to, Ni to, Mo to, N maximum, Fe rest.

Stainless steel refers to the steel that is resistant to weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to corrosion by weak corrosive media is often called stainless steel, and the steel that is resistant to chemical media corrosion is called acid-resistant steel.

SUS is a Japanese material standard, and 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China.

Japan also uses the American name as SUS304

1. The yield strength is different: SUS316 is 210 (N mm2), while 316L is 180 (N mm2).

2. The tensile strength is different: SUS316 is 520 (N mm2), while 316L is 480 (N mm2).

3. Different molybdenum content: the molybdenum content in SUS316 is slightly lower than 316L.

4. Different heat resistance: At the same temperature, the heat resistance of SUS316 is higher than that of 316L.

Features of the 316L:

The corrosion resistance of 316L is better than that of 304 stainless steel, which can be fully reflected in the production process of pulp and paper, because it has good resistance to chloride erosion, so it is also resistant to the erosion of the ocean and the corrosive industrial atmosphere, and is mostly used in machinery and equipment in the marine environment.

In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316L stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is better not to act continuously 316L stainless steel, which has good heat resistance when used continuously outside this temperature range. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and can be used in the above temperature ranges.

The above content refers to Encyclopedia-316L stainless steel.

Encyclopedia - SUS316 stainless steel.

The anti-rust effect of SUS316 is better than that of SUS304 (also known as 304 stainless steel).

SUS316: austenitic stainless steel, this material is not easy to be oxidized by air in the natural environment of acid and alkali, and is not easy to be eroded in the natural environment of humidity and cold. In addition, it has very good properties due to the relatively high chemical elements, such as:

Compressive strength, can withstand high temperatures, and can continue to work in extreme high temperatures in natural environments, etc.

304:304 stainless steel is a common material in stainless steel, with a density of; It is also called 18 8 stainless steel in the industry, which means that it contains more than 18% chromium and more than 8% nickel; High temperature resistance 800, with good processing performance, high toughness characteristics, widely used in industry, furniture decoration industry and food and medical industry.

The content of 3161 and 316 is different, the heat resistance is different, and the heat treatment method is different. First of all, the content of the two is different. The molybdenum content in 316L stainless steel is slightly higher than that in 316 stainless steel.

The upper limit of the carbon content of 316 is , and the upper limit of the carbon content of 316L is, the higher the C content, the more likely it is to cause intergranular corrosion. The L of 316L refers to low carbon, as a low-carbon series of 316 steel grades, in addition to having the same characteristics as 316 steel, its grain boundary corrosion resistance is excellent. The second is the difference in heat resistance between the two.

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.
