AISI 430 F is a stainless martensitic steel, also known as X14CrMoS17 or 1.4104. It is characterized by good corrosion resistance and excellent machinability, making it ideal for the production of precision parts such as screws and nuts. This steel contains approximately 16-18% chromium and 1% molybdenum, which enhances its corrosion resistance. Additionally, it contains sulfur to improve machinability. 1.4104 is commonly used in the automotive industry, mechanical engineering, and the manufacturing of household appliances.
