TorqBolt stocks high pitting resistant Super Duplex Fasteners. Super Duplex contains roughly 25% chromium, 4% molybdenum, 7% nickel designed for demanding applications, which require high strength. It has outstanding resistance for pitting and crevice corrosion in seawaters and thus it has number of applications in marine Industry. It is advisable not to use this type of alloy for temperatures ranging higher than 300 Degrees Celsius. it is mainly used in oil and gas industry, offshore platforms, heat exchangers, vessels and high pressure RO plants. It has a very good weldabillity, it can joined to itself or other material.
