Three: the scope of application, the field of application:

316L stainless steel is added with MO, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are particularly good, and can be used under harsh conditions; Excellent work hardening (non-magnetic). Excellent strength at high temperatures. 316L stainless steel is an austenitic stainless steel and cannot be strengthened by heat treatment.

It has good strength, plasticity, toughness and cold formability, as well as good low-temperature properties. Due to the addition of 2% MO on the basis of Cr18Ni8, the steel is endowed with good resistance to reducing media and pitting resistance. It has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts and seawater.

In reducing acidic media, its corrosion resistance is much better than that of 304

Four: Overview. The corrosion resistance of stainless steel 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. In intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is better not to act continuously on 316 stainless steel, but when 316 stainless steel is used continuously outside of this temperature range, the stainless steel has good heat resistance.

316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and can be used in the above temperature ranges. Annealing is carried out in the temperature range of 1850-2050 degrees, followed by rapid annealing, followed by rapid cooling. It has high temperature resistance, easy processing, and high strength.

316L stainless steel, no post-weld annealing is required.

Difference Between Stainless Steel 304 and 316.

304 stainless steel: resistant to chemical oxidation; 304 is the material that must be used in the national pressure cooker standard, and the standard material of the stainless steel pressure cooker is more than 304, because there are not many pressure cooker production factories approved by the state, so these factories are very honest, all of them are 304 stainless steel materials used in the minimum standard.

316 Stainless Steel: High-grade supplies are made with 10% nickel to make stainless steel more durable and corrosion-resistant, this stainless steel is called 18-10 stainless steel, that is"Medical stainless steel"There is no precipitation of metal ions at all.

First of all, 316 stainless steel contains MO, which is more corrosion resistant than 304 stainless steel in a high-temperature environment, so in a high-temperature environment, engineers generally choose 316 material parts.

Secondly, there is also a difference between the two in terms of grade; 304 stainless steel corresponds to Chinese grade 0Cr18Ni9; 316 stainless steel corresponds to the Chinese grade 0Cr17Ni12Mo2.

Thirdly, 316 mainly reduces the CR content, increases the Ni content, and increases the MO2% by 3%. Therefore, its corrosion resistance is stronger than that of 304, suitable for use in chemical, seawater and other environments, similarly, the cost of 316 is also higher than that of 304, and generally 316 is used in places with higher requirements to replace 304.

The differences between 304 and 316 stainless steel include different chemical compositions, different corrosion resistance, different properties, different application ranges and different applications.

1. The chemical composition is different

304 does not have molybdenum elements, while 316 has molybdenum elements, and the carbon, chromium and nickel content of 304 stainless steel and 316 stainless steel are also different.

2. The corrosion resistance is different

304 contains only 9% of nickel, while 316 contains 12% of nickel, because the pants are classified as 316 is food grade, so the corrosion resistance of 304 is worse than that.

3. The performance is different

304 has better corrosion resistance, acid resistance, alkali resistance, etc., while 316 has better chloride corrosion resistance and heat resistance due to the addition of molybdenum elements.

4. The scope of application is different

304 is widely used to make pots and pans, etc., while 316 is widely used in the food industry, medical industry, watch industry, etc.

5. The element grades are different

The Chinese element corresponding to 304 stainless steel is 0cr18ni9, and the Chinese element corresponding to 316 stainless steel is 0cr17ni12mo2. Void car.

Hello, the following is the answer to your query, I hope it will help you, the difference between 304 and 316 stainless steel is the chemical composition and use. 1.Ingredients of Zheng Pai Xue:

304 unbushed rust steel contains 18% chromium and 8% nickel, while 316 stainless steel contains 16% chromium, 10% nickel and 2% molybdenum. The addition of molybdenum gives 316 stainless steel better corrosion resistance. 2.

Corrosion resistance: 316 stainless steel has better corrosion resistance than 304 stainless steel, especially for corrosive media such as seawater and chloride, which is more widely used in the marine environment and chemical industry. 3.

Strength: 316 stainless steel has higher strength and heat resistance than 304 stainless steel, so it is more widely used in high-temperature environments. 4.

**: 316 stainless steel is more expensive than 304 stainless steel because it is more expensive to manufacture. In short, depending on the specific application scenario and requirements, the choice of 304 or 316 stainless steel may be a suitable choice.

The above is all my reply, I hope I can help you and wish you a happy life

Hello, 304 and 316 stainless steel are both commonly used stainless steel materials, and their main difference is that their composition and properties are different. First of all, the main components of 304 stainless steel are 18% chromium and 8% nickel, while the main components of 316 stainless steel are 16% chromium, 10% nickel and 2% molybdenum. Therefore, 316 stainless steel is more resistant to corrosion than 304 stainless steel, especially in seawater environments.

Secondly, the tensile strength and yield strength of 316 stainless steel are higher than those of 304 stainless steel, but its hardness and magnetic properties will be slightly reduced. In addition, 316 stainless steel is more suitable for use in high-temperature environments than 304 stainless steel because it has higher heat resistance and better oxidation resistance. In general, the choice between 304 and 316 stainless steel depends on the specific application and needs.

If you need better corrosion resistance and high temperature resistance, then you can choose Qingwei 316 stainless steel, but the cost may be higher. There are many types of stainless steel, such as etc., all of which have different compositions and properties. Choosing the right stainless steel material needs to be comprehensively considered according to the specific application scenario and the needs of Bilun.
