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.
