What is the difference between the Su33 and the Su35?

The Su-33 is a third-generation fighter. The Su-35 has already reached three and a half generations.

The Su-35 has a new engine and fire control system. Part of the new air-to-air and air-to-surface missiles were used.

The fuselage of the Su-35 was also enlarged.

SUS430 martensitic stainless steel, SUS304 austenitic stainless steel.

SUS430 has the characteristics of corrosion resistance, mechanical properties and thermal conductivity, but it is brittle at room temperature, and has stainless properties in atmosphere, water steamers and other media, but the stainless property is insufficient when the medium contains higher chloride ions. It has good corrosion resistance in oxidizing acid solutions, especially in dilute Hno3. Dilute Hno3 related parts can be crafted.

It can also be used to make oxidation-resistant parts below 900 degrees, scatterers, furnace parts, oil nozzles, etc. Because the brittle transition temperature is above room temperature and is sensitive to notching, it is not suitable for making components of load-bearing equipment below room temperature.

1. Advantages and stability.

433 stainless steel is cheaper than SUS304 because it does not need to add nickel. Because there is no need to add nickel and molybdenum, even if the price of these two metals rises, it will not be affected by the base sales.

2. Advantages of thermal conductivity.

The thermal conductivity of 433 stainless steel is about 30% higher than that of SUS304, so it is used in the application of cooking products. More time and energy saving, coupled with its good magnetic conductivity, the use of Changfengqi on the induction cooker can show the advantages of the material, and the use effect is better.

3. The material resistance of stainless steel 443 is as follows: the matrix has a potting resistance index of 300mv, which is equivalent to that of 304 stainless steel, with high thermal stability and good tensile performance.

It's different, one with cu and one without cu, and the purpose is different.

SUS304CU stainless steel has been used for the production of fluid transfer machinery and equipment for heat exchanger special stainless steel tubes and plates; It is precisely because of the strong environmental adaptability of SUS304Cu material that it can be suitable for environments including no rust at room temperature and pressure, corrosion resistance, heat resistance, high temperature and low temperature resistance, high hardness and high strength, smooth and beautiful decoration. It is widely used in petrochemical industry, chemical fertilizer, electric power, boiler heat exchanger, shipbuilding, environmental protection, mechanical processing, papermaking, food and beverage and other fields.

The chemical composition and mechanical properties of SUS304Cu are shown below

The only difference between SUS304CU and SUS304 is the difference in chemical composition, as shown in the figure below

One with copper and one without copper.

SUS430, Japanese SUS series stainless steel. SUS430 (F FR) stainless steel corresponds to the national standard with the steel grade of 1CR17. The tensile strength is greater than 450, the yield strength is greater than 205, and the HBS is less than 183 (the data is annealed).

It is often used as building decoration, heavy oil burner parts, etc. 430LX adds Ti or NB to 430 steel and reduces the C content, which improves the processing and weldability. It is used in hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.

430 stainless steel, steel + more than 12% chromium can prevent oxidation caused by natural factors, called stainless steel, in the JIS code 430, so it is also called 430 stainless steel. However, 430 stainless steel cannot resist the oxidation caused by chemicals in the air, because there are more and more acidic chemicals in the air, so 430 stainless steel is often used for a period of time, and it will still oxidize (rust) due to unnatural factors.

It reads as follows:

SUS304 belongs to stainless steel; Non-magnetic or weak-magnetic.

SUS430 belongs to stainless steel iron; It is a strong magnetic.

The Japanese grade SUS430 corresponds to the Chinese grade 1CR17. It is ferritic stainless steel: stainless steel with a ferritic structure as the main body in use.

The chromium content is about 17%, and it has a body-centered cubic crystal structure. 1Cr17 does not contain nickel, it has the characteristics of large thermal conductivity, small expansion coefficient, good oxidation resistance, excellent stress corrosion resistance, etc., and is mostly used in the manufacture of parts and components that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion. This type of steel has disadvantages such as poor plasticity, significantly reduced plasticity and corrosion resistance after welding, thus limiting its application.

SUS304 belongs to stainless steel, SUS430 belongs to stainless steel, iron is non-magnetic or weak magnetic, and the latter is strong magnetic.

SUS304 belongs to the Japanese standard austenitic stainless steel, and SUS430 belongs to the Japanese standard ferritic stainless steel, and both standards are implemented "JIS G4303-2005".

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

The chemical composition of SUS430 is shown in the following figure:

SUS304 refers to 304 stainless 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.

And SVS304 is a pirated and fake version of SUS304. The quality is worse than SUS304, and it is a pirated stainless steel produced by some merchants by exploiting loopholes, so don't buy the wrong pirated SVS304 when buying stainless steel materials

su27：

The top of the SU27 tail is sloped, while the SU30 33 35 is flat.

The SU27 photosensor is in the middle, while the SU30 33 35 is on the right.

The SU27 front wheel is single-wheeled, while the others are two-wheeled.

The Su27 is single-seater, with the exception of UB UBK.

SU30: As long as you see the tandem two-seater version, except for the SU27UB UBK (through the characteristics mentioned above, the tail wing, landing gear, fuel pipe, photoelectric sensor position, etc.), it is all SU30.

Su33: single-seat carrier-based aircraft.

Three-wing design, i.e. a pair of ducklings in front of you, is also available for the SU30MKI and a few SU27s (like the Su271B). But through the single and double seats, and the tail wing, photoelectric sensors, fuel pipes and other characteristics, it can be ruled out whether or not SU27 30. In addition, there are the following characteristics of carrier-based aircraft:

There are folding wings. There is a stout landing gear.

With tail hook (landing hook).

The tail cone is comparatively shorter.

SU35: Compared to SU27, the rear wing is flat.

Compared with the SU30, it is a single-seater version.

Compared with the Su33, the official version of the Su35 does not have canards (the Su35 has only one verification aircraft with a three-wing design).
