ISO6931-1
ISO 6931-1 4310-301 is a stainless austenitic spring steel known for its good mechanical properties and excellent corrosion resistance. It is commonly used in springs, clips, and other high-performance applications where both strength and corrosion resistance are required. The material contains chromium and nickel as main alloying elements, and may include a small amount of molybdenum for additional corrosion protection. It offers good formability and strength and is typically employed in environments with moisture or chemicals.
