430 Stainless Steel Chemical Composition

As a type of ferritic steel, 430 stainless steel demonstrates its slight corrosion resistance and excellent durability. It is typically used for components and surfaces of kitchen appliances, and automotive trims. A large amount of coolant is required for machining due to the edge galling resulting from the low thermal conductivity of 430 stainless steel.
