Product Discription:
Features:
Duplex stainless steel corrosion resistant. They have strong resistance to inter-granular corrosion. Even in chloride and sulfide environments, duplex stainless steels show very high resistance to stress corrosion cracking. Duplex stainless steel work hardening alloy. Their micro-structure consists of austenitic phase and ferritic phase. Therefore, duplex stainless steel shows the characteristics of austenitic and ferritic stainless steel. This combination of properties may mean some compromise compared to pure austenite and pure ferrite.
Use of S31803 duplex stainless steel:
S31803 is generally used in the production of chemical, chemical fertilizer and chemical fiber and other industrial equipment,such as containers, pipes and structural parts.
