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 and belongs to 430 ferritic stainless steel. It has 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 commonly used in the production of household appliances, heat-resistant appliances, burners, household 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.
304 and 316 are both austenitic stainless steel, and 316 is added molybdenum in 304 stainless steel, so the ability of 316 stainless steel to resist seawater and rust is much better than 304.
The difference between 304, 316 and 430 is that the antirust performance is different. Since 304 and 316 contain elements such as nickel and molybdenum in addition to chromium, and are non-magnetic, the antirust performance of 304/316 austenitic stainless steel is better than that of stainless steel. 430 stainless steel is much better, and the price is much higher.
Can 430 stainless steel magnets absorb it?
304, 316 are not magnetically conductive, so they cannot be attracted by magnets. Generally, it will not generate heat in a high-voltage electromagnetic environment, so it is used more. Martensitic and 430 ferritic stainless steel and precipitation hardening stainless steel are magnetic and can be attracted by magnets.
Will 430 stainless steel rust?
430 stainless steel cannot resist the oxidation caused by chemical substances in the air. Because there are more and more acidic chemical substances in the air, 430 stainless steel will still be oxidized (rusted) due to unnatural factors after a period of time. Condition.
Which is better, 430 stainless steel or 304?
304 austenitic stainless steel has excellent corrosion resistance and is not magnetic. Relatively speaking, austenitic stainless steel 304 is better than 430 ferritic stainless steel.
How much is 430 stainless steel more expensive than 304?
Generally speaking, austenitic stainless steel 304 is twice as expensive as 430 stainless steel.
