The properties of stainless steel’s ferritic and austenitic groups are essentially combined in duplex steels. Nitrogen-enhanced duplex stainless steel is Duplex 2205 Round Bar. In accordance with the definition of a family of stainless steels that do not belong to the categories of fully austenitic grades, such as 304 stainless steel, or solely ferritic grades, such as 430 stainless steel, the stainless steel grade 300 is referred to as Duplex. The microstructure of the stainless S31803 Duplex Spring Steel Bar is made up of austenite pools that are surrounded by a continuous ferrite phase. The alloy grade 2205 Duplex Stainless Steel Round Bar was created to address common issues with corrosion associated with austenitic grade 300 series stainless steels.
The numerous applications of 2205 Duplex Rod are as follows: healthy overall corrosion tolerance; high power; excellent weldability and workability; resistance to sulphide stress corrosion; resistance to chloride pitting and crevice corrosion; and high resistance to chloride stress corrosion cracking. The Duplex 2205 Threaded Rod, which can be used for a variety of things, is harder to machine and has cutting speeds that are about 20% slower than those of grade 304.
