Difference and application of stainless steel 430, 304, 316
Mar 04, 2020| 430 ferritic stainless steel contains more than 12% of steel, which can prevent oxidation caused by natural factors. It is called stainless steel and belongs to 430 ferritic stainless steel. It has a low thermal expansion rate and excellent formability and oxidation resistance. The JIS code is 430, so it is also called 430 stainless steel.

Application of 430 ferritic stainless steel:
430 stainless steel (16Cr) is often used in the manufacture of household appliances, heat-resistant appliances, burners, household appliances, type 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 austenitic stainless steel. 316 is added with molybdenum in 304 stainless steel, so the ability of 316 stainless steel to resist seawater and embroidery is much better than 304. The difference between 304, 316, and 430 is the different rust prevention performance. Because 304 and 316 contain elements such as nickel and molybdenum in addition to chromium, they are non-magnetic. Therefore, the rust prevention performance of 304/316 austenitic stainless steel is much better than 430 stainless steel, and the price is much higher.
Can 430 stainless steel magnets hold it?
304 and 316 are not magnetically permeable and cannot be attracted by magnets. Generally, they do not generate heat in a high-voltage electromagnetic environment. Therefore, they are used more. Martensitic and 430 ferritic stainless steels. Precipitation hardened stainless steels are magnetic and magnets can absorb them. live.
Will 430 stainless steel rust?
430 stainless steel can not resist the oxidation caused by chemicals in the air. Due to the increasing number of acidic chemicals in the air, after 430 stainless steel is not used for a period of time, it will still be oxidized due to unnatural factors (rust) Case
Which is better, 430 stainless steel or 304?
304 austenitic stainless steel has excellent corrosion resistance and is non-magnetic. Relatively speaking, austenitic stainless steel 304 is better than 430 ferritic stainless steel.
How much is the price of 430 stainless steel compared to 304?
In general, 304 austenitic stainless steel is twice as expensive as 430 stainless steel
