S31803 ASTM A240 S32205 Duplex Steel Plate DSS Plate 3mm -10mm
S31803 ASTM A240 S32205 Duplex Steel Plate DSS Plate 3mm -10mm
Duplex stainless steel
Duplex stainless steel offers excellent resistant to corrosion and very high mechanical strength. The high corrosion resistance of duplex stainless steel ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, more compact system design and less welding.
