Comparison of 304 stainless steel and 430 stainless steel:
1. Corrosion resistance: 430 stainless steel contains chromium, basically no nickel metal, 304 stainless steel contains more chromium nickel metal, so 430 stainless steel corrosion resistance is not as good as 304 stainless steel.
2. Stability performance: 430 stainless steel is ferritic form, 304 stainless steel is austenitic form, 304 stainless steel is more stable than 430 stainless steel.
3. Toughness: 304 stainless steel has strong toughness, and the brightness is stronger than that of 430 stainless steel.
4. Thermal conductivity: the ferrite of 430 stainless steel has better thermal conductivity than the austenitic of 304 stainless steel.
5. Mechanical properties: 430 stainless steel Zhaofan adds stable chemical element titanium, and the mechanical properties of the weld part are better than those of 304 stainless steel.
430 stainless steel use field:
Stainless steel is mainly used for building decoration, fuel burner parts, household appliances, and home appliance parts.
2. Add 430F steel grade with easy cutting performance to 430 steel, which is mainly used for automatic lathes, bolts and nuts.
3. Add Ti or NB to 430 steel, reduce the C content to become 430LX, improve the processing performance and welding performance, mainly used in hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.
304 stainless steel use field:
Stainless steel has the characteristics of high temperature resistance, good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medical industries.
Stainless steel has strong corrosion resistance and is widely used in the production of equipment and parts that require good comprehensive properties (corrosion resistance and formability).
Summary: 430 stainless steel has good thermal conductivity and mechanical properties, and 430 stainless steel is better in the fields of building decoration, fuel Jingchai old burner parts, household appliances, household appliance parts, etc.; 304 stainless steel has strong toughness and corrosion resistance, and it is better in industries that require corrosion resistance such as industrial and food medical.

Anonymous users2024-02-051. The corrosion resistance is different: 430 stainless steel contains chromium, basically no nickel metal, and 304 stainless steel contains more chromium and nickel metal, so the corrosion resistance of 430 stainless steel is not as good as that of 304 stainless steel.
2. The stability performance is different: 430 stainless steel is ferritic form, 304 stainless steel is austenitic form, and 304 stainless steel is more stable than 430 stainless steel.
3. Different toughness: 304 stainless steel has strong toughness, which is stronger than that of 430 stainless steel.
4. Different thermal conductivity: the ferrite of 430 stainless steel is better than the austenitic thermal conductivity of 304 stainless steel.

So what does 430 stainless steel do?
1. 430F is a steel grade with easy cutting performance on 430 steel, which is mainly used for automatic lathes, bolts and nuts.
2. 430LX adds Ti or NB to 430 steel to reduce C content, which improves the processing performance and welding performance, and is mainly used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.
3. Because of its chromium content, it is also called 18 0 or 18-0. Compared to 18 8 and 18 10, it contains slightly less chromium and has a corresponding reduction in hardness.
That's all there is to know about what 430 stainless steel does.

Anonymous users2024-02-03The difference between stainless iron and stainless steel: Compared with stainless steel, stainless iron mainly lies in whether it contains nickel or not. Stainless iron generally refers to SUS430 in Japan, 1Cr17 in China, and the main chemical composition is:
C: <, Si: <, Mn<100, P:, S<, Ni: <, ferritic stainless steel.
The so-called "stainless iron" is to process the scrap iron, lead, steel, etc. through the secondary return to the furnace, and the traditional detection method is to use magnetite.
And this product can not be distinguished by traditional methods, naturally it is hidden from the world, covering a large number of engineering materials, so it has entered one decoration site after another, and climbed one luxury curtain wall after another.
The name "stainless iron" was born after the "Focus Interview"**, and occupies about 65% of the market share, while the real national standard SUS304 stainless steel products have no market due to their high **. Obviously, the tensile strength of "stainless iron" is not up to the strength of stainless steel, which is very easy to lead to accidents.

Anonymous users2024-02-02Difference Between 430 Stainless Steel and 304 Stainless Steel:
1. Corrosion resistance.
430 stainless steel contains chromium and is basically nickel-free. 304 stainless steel contains more chromium and nickel metals, so the corrosion resistance of 430 stainless steel is not as good as that of 304 stainless steel.
2. Stability.
430 stainless steel is ferritic, 304 stainless steel is austenitic, 304 stainless steel is more stable than 430 stainless steel.
3. Toughness. 304 stainless steel has strong toughness and is stronger than 430 stainless steel.
4. Thermal conductivity.
The ferrite of 430 stainless steel has better thermal conductivity than that of 304 stainless steel.
5. Mechanical.
430 stainless steel is added with the stable chemical element titanium, and the mechanical properties of the weld part are better than those of 304 stainless steel.
Difference Between Galvanized Sheet and Stainless Steel:
1. Different concepts: galvanizing refers to coating a layer of metal zinc on the surface of the steel plate, the purpose is to prevent the surface of the steel plate from being corroded and prolong its service life. 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.
2. Different fields of application: galvanized sheet strip products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery and commercial industries. Stainless steel is mainly used in the construction field, is one of the strongest materials in the construction of metal materials, and is also used in food processing, catering, brewing and chemical fields with high requirements for hygienic conditions.
3. The processing technology is not the same: galvanization is mainly to coat a layer of dense zinc on the surface of steel. Stainless steel is the addition of other metal elements inside the steel, so that the internal structure changes and the product does not rust. <>

Stainless steel refers to a general term for steel that has certain chemical stability in atmosphere, water, acids, alkalis and salts, or other corrosive media. Generally, steel that is resistant to corrosion by weak media such as atmosphere, steam, and water is called stainless steel. >>>More
There are two methods, one is to use passivation paste, which is specially used to clean short stainless steel welds, which only need to be applied to the weld for 20 minutes and wiped off; The other is for more welds, first put the workpiece into the mixture of nitric acid and hydrofluoric acid to soak and clean for 15 minutes, take it out and rinse it with water, and then put it into nitric acid to passivate for 20 minutes, take it out and rinse it clean.
The stainless steel cutting board is very easy to use, the hardness is very high-quality and very good, and it is very practical. >>>More
The production and processing of stainless steel words need to go through a number of strict processes, and its production is more difficult in metal words. First of all, the stainless steel word is to be cut, combined with wire cutting, laser cutting and water cutting. Then weld with a welding torch, then grind and wrap the edge, and at this point the glyph is basically out. >>>More
