SUS430 belongs to the Japanese standard ferritic stainless steel, which is a stainless steel grade, and the executive standard: JIS G4303-1012

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

SUS430 stainless steel is widely used in the manufacture of chemical equipment for the production of nitric acid, such as absorption towers, nitric acid heat exchangers, acid tanks, conveying pipes and tanks, as well as industrial pipes and tableware for food and winemaking, because of its good corrosion resistance in oxidizing acid solutions, especially nitric acid.

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 vaporizer and other media, but the stainless property is insufficient when the medium contains high 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.

SUS430 application field: mainly used in the production of Hno3 chemical equipment, such as absorption towers, heat exchangers, storage tanks, etc., thin plates are mainly used for building materials, daily necessities, automotive decorations, etc., for oxidation parts below 900 degrees, dispersers, furnace parts, oil nozzles, etc. Although SUS430 tubing is a mature material, the challenges of the SUS430 tubing range of applications are constantly changing, and those industries that have higher requirements for the strength, corrosion resistance and cost control of SUS430 tubing have higher requirements for the process and quality of SUS430 tubing.

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.

SUS304 Chemical Composition: Carbon C : Silicon Si : Chromium Cr :; Manganese Mn : Nickel Ni :; Phosphorus p : sulfur s :

Due to its high nickel content and austenitic single-phase structure at room temperature, it has high corrosion resistance compared with CR13 stainless steel, high plasticity and toughness at low temperature, room temperature and high temperature, as well as good cold work forming and weldability. However, at room temperature, the strength of Qiaoshi is low, the intergranular corrosion and stress corrosion tendency are large, and the machinability is poor.

SUS410L ferritic stainless steel. Chromium content 12% 30%. Its corrosion resistance, toughness and weldability improve with the increase of chromium content, and its chloride stress corrosion resistance is better than that of other types of stainless steel.

The ferite structure of low carbon is excellent, and the bendability of the weld part is excellent.

SUS410 is made of stainless steel.

SUS410 is a nickel-free stainless steel, which is martensitic stainless steel, with good hardenability, it has high hardness, toughness, good corrosion resistance, thermal strength and cold deformation performance, and good shock absorption. High or low temperature tempering is required, but tempering between 370-560 should be avoided.

The advantages of SUS410 stainless steel: large thermal conductivity, small expansion coefficient, good oxidation resistance, excellent stress corrosion resistance and other characteristics. The application of external refining technology (AOD or VOD) can greatly reduce interstitial elements such as carbon and nitrogen.

SUS410 is a Japanese grade; 1Cr13 is the corresponding Chinese grade; X10Cr13 is the corresponding German grade; 410 is the corresponding U.S. grade.
