One of the key properties of 430 stainless steel is its ability to resist oxidation and rust in humid or mildly corrosive environments.  It contains at least 16% chromium, which forms an invisible protective layer on the surface to prevent rust.  Another advantage is its resistance to high temperatures (up to 1500°F) without losing strength or becoming brittle.  It also has good ductility and formability, making it easy to shape into different products.  Industries where 430 stainless steel is frequently used include aerospace engineering, medical device manufacturing, petrochemical processing plants, and marine applications such as marine fittings.  However, welding 430 stainless steel can be challenging due to its high chromium content.  After welding is done, be sure to clean them thoroughly with a wire brush to remove any discoloration caused by heat exposure during the welding process.
