430 stainless steel is the general-purpose steel with good corrosion resistance, with better thermal conductivity than austenite, and with smaller thermal expansion coefficient than austenite. And because of its heat resistance and containing titanium, a stable chemical element, the mechanical properties of welding parts are good. Because the price is relatively low, 430 stainless steel has become a choice of replacing 304 stainless steel in many application fields. However, compared with 304, 430 still has its limitations in the corrosion resistance and deep processing performance.
430 Stainless Steel is known as stainless steel for its chromium content 16%-18%, which is enough to prevent oxidation caused by natural factors. According to JIS standard, its code number is 430, therefore it’s called 430 stainless steel. However, 430 stainless steel can not resist the oxidation of chemical substances in the air, so 430 stainless steel will still be oxidated (rusted) due to unnatural factors after a while of use. Room temperature structure of 430 Stainless Steel is ferrite, with no martensite. Its corrosion resistance is strong in oxidizing environment, but it has tendency of intergranular corrosion, while is weak in liquid of non-oxidizing acid and activation.
Density Components

Industry Application
430 stainless steel is often applied to building decoration, fuel burner parts, household appliances, home appliance parts. Most household appliances are made of 430 stainless steel. 430F is a steel with easy cutting performance based on 430, mainly used in automatic lathe, bolts and nuts. 430LX is gained through 430 steel to add ti or NB to reduce the C content, improving the processing performance and welding performance, mainly used in hot water tanks, heat supply systems, sanitary appliances, durable home utensils, bicycle, flywheel and so on.
