Chromium is the essential component usually present in considerable amounts in most steel grades and in duplex S31803 fasteners, it occupies a whopping 22-23% of the total composition, making it the most predominant additive. This addition grants the alloy corrosion resistance and significant hardenability. Apart from chromium, the primary element of iron also imparts hardness and strength to the steel grade. Two elements are not enough to stabilize the fasteners for performing in various conditions and therefore, there are other elements present, which include molybdenum, sulfur, phosphorus, nickel, manganese, carbon, nitrogen, etc. The incorporation of nitrogen proves to be essential in making the duplex S31803 fasteners to be cost-effective while bestowing them with enhanced resistance against corrosion.

With both ferritic and austenitic microstructure, the properties exhibited by the duplex S31803 fasteners are much better than any other normal stainless steel grade fasteners. This can be seen through its performance in chloride and sulfide environments, where it resists the corrosive action of both these ions impressively without letting it affect its functionality in any way. The S31803 fasteners are excellent in resisting all forms of corrosion such as pitted or crevice or even stress corrosion and the number of corrosive liquids and gases they tackle is remarkable and denotes just how efficient they are when dealing with corrosive agents. Strength is another notable feature displayed exceptionally by these fasteners and it is this trait that allows it to function even in stressful conditions. With properties as such the durability is enhanced, enabling them to be stable in diverse operating conditions.
