Duplex Steel S31803 nuts possess high strength, corrosion resistance, and durability, with excellent suitability in harsh conditions. Their microstructure is duplex-phase, incorporating the advantages of austenitic as well as ferritic steel with enhanced toughness and stress corrosion cracking resistance. The S31803 nuts also have high pitting and crevice corrosion resistance to ensure sound performance in marine, chemical, and industrial uses. Their strength supports lighter and cost-saving designs due to reduced weight compared to conventional materials.
