What are the characteristics and benefits of Duplex Steel UNS S31803 Forged Fittings?
Duplex Steel UNS S31803 Forged Fittings possess many beneficial characteristics that contribute to their appeal in numerous industries.UNS S31803 Forged Fittings are known for its high tensile strength and it contains the features of both the ferritic and austenitic stainless steel. Their unique microstructure imparts superior mechanical properties such as increased tensile and yield strengths to allow for high pressure environments as well as aggressive media environments such as oil & gas, chemical processing and marine industries.
Duplex Steel UNS S31803 Forged Fittings offer exceptional toughness and flexibility, enabling them to withstand sudden impacts without cracking under dynamic stress or shifting operational conditions. Their high resistance to stress corrosion cracking as well as pitting makes them durable and reliable even in extreme working conditions. It also improves dimensional stability during varying temperatures due to its low thermal expansion coefficient.
Heating and heat treatment processes of forgings further improve the properties of the Duplex Steel UNS S31803 Forged Fittings by minimizing imperfections and improving grain structure which results in greater strength and fatigue limits and also special shapes and dimensions required for a number of specific applications. This makes Duplex Steel UNS S31803 Forged Fittings suitable for critical applications.
