430 ferritic stainless steel
Steel with a chromium content of more than 12% can prevent oxidation caused by natural factors. It is called stainless steel. It is a 430 ferritic stainless steel with low thermal expansion rate, excellent formability and oxidation resistance. The code name in JIS is No. 430, so it is also called 430 stainless steel.
Application of 430 ferritic stainless steel
430 stainless steel (16Cr) is often used to make household appliances, heat-resistant appliances, burners, home appliances, class 2 tableware, kitchen sinks, exterior decoration materials, bolts, nuts, CD rods, and screens.
The difference between 430 stainless steel and 304, 316 austenitic stainless steel
430 stainless steel and 304, 316 austenitic stainless steel are identified by spectral analysis and chemical element analysis.
Both 304 and 316 are austenitic stainless steel, and 316 has molybdenum added to the 304 stainless steel. Therefore, the seawater and rust resistance of 316 stainless steel is much better than that of 304.
The difference between 304, 316 and 430 lies in the rust resistance. In addition to chromium, 304 and 316 also contain elements such as nickel and molybdenum, and are non-magnetic. Therefore, the rust resistance of 304/316 austenitic stainless steel is better than 430 stainless steel is much better, and the price is much higher.
Can the 430 stainless steel magnet hold it?
304 and 316 are not magnetic and cannot be attracted by magnets. Generally, it does not generate heat in a high-voltage electromagnetic environment, so it is used more. Martensite, 430 ferritic stainless steel, precipitation hardening stainless steel are magnetic, and magnets can attract them.
Will 430 stainless steel rust?
430 stainless steel cannot resist the oxidation caused by chemicals in the air. Because there are more and more acidic chemicals in the air, 430 stainless steel will still be oxidized (rusted) due to unnatural factors after it is not used for a period of time. Happening.
Which is better, 430 stainless steel or 304?
304 austenitic stainless steel has excellent corrosion resistance and no magnetism. Relatively speaking, austenitic stainless steel 304 is better than 430 ferritic stainless steel.
How much more expensive is the price of 430 stainless steel compared to 304?
Generally speaking, austenitic stainless steel 304 is twice as expensive as 430 stainless steel.
