SUPER DUPLEX STEEL S32750 / S32760 FASTENER MECHANICAL PROPERTIES
- Super Duplex stainless steels exhibit PREN value higher than 40.
- Combines most desirable characteristics of both super-ferritic and Super-Austenitic steel.
- Has excellent resistance to chloride SCC, pitting, crevice, and general corrosion, and carbide-related inter-granular corrosion.
- Possesses high strength & impact strength.
- Has high thermal conductivity and a lower coefficient of thermal expansion compared to Super Austenitic steels.
FABRICABILITY :
- It should be hot worked in the range of 1250-1000 deg C, followed by a solution annealing at 1100 deg C and rapid quench.
- It can be cold formed using methods similar to those commonly used for Stainless Steel. The primary difference is that the high yield strength makes it necessary to have higher forming forces, increased radius of bending, and increased allowance for spring back.
- Deep drawing, stretch forming and similar processes are difficult to perform.
WELDABILITY :
- It possesses good weldability and can be welded to itself and other materials by Shielded Metal Arc Welding (SMAW), gas tungsten Arc Welding (GTAW), Plasma Arc Welding (PAW), or Submerged Arc Welding (SAW).
- Surfaces must be clean before welding.
- Preheating is not necessary, except to prevent condensation on cold metal.
- The recommended heat input should be nearly about 0.3-1.5K1/mm
- The interpass temperature should not exceed 150 deg C.
- The root should be shielded with commercial Ar or 90%N2 / 10%H2 purging gas for maximum corrosion resistance.
CORROSION RESISTANCE :
- It is highly resistant to carbide related inter-granular corrosion due to its low carbon content which lowers the
- risk of carbide precipitation at the grain boundaries during heat treatment. Its critical pitting temperature (CPT) is superior to that of 904L.
- It has excellent resistance to crevice corrosion and SCC,
- Extremely resistant to uniform corrosion by organic acids such as formic and acetic acid and also to inorganic acids, especially those containing chlorides.
- Excellent corrosion resistance against highly corrosive acids like Sulphuric, Nitric, Phosphoric acids.
APPLICATION :
- Oil and gas industry.
- Petrochemical industries ( polymerization reactor cycle pumps and pipework)
- Offshore platforms (heat exchangers, process and service water systems, fire-fighting systems, and injection and ballast water systems)
- Chemical process industries (heat exchangers and vessels)
- Desalination plants (high-pressure RO-plant and seawater piping)
- Fertilizers (Recirculation tanks, sedimentation tanks, phosphate reactor recirculation pumps)
- Power industry FGD systems
- Utility & industrial scrubber systems (absorber towers, ducting, piping)
- Mining/ Extraction ( hot slurry pipework, acid leach mining)
- Sewage (critically important pipelines.)
- Engineering applications (pressure vessels,)
