margin-bottom: 20px; font-size: 13px;"><ul><li><b>Balanced Microstructure and High Strength:</b> Duplex Steel UNS S31803 Plates is a dual-phase austenitic and ferritic structure and improves the mechanical performance. They have almost twice the yield strength of standard stainless steel grades. This enables the use of reduced plate thickness with no harm to structural integrity. The outcome is a greater load-bearing efficiency of heavy-duty industrial uses.</li></ul></div></div><p><ul><li><b>Excellent Corrosion Resistance:</b> These plates have very high resistance to pitting, crevices and stress corrosion cracking in chloride rich locations. Its high levels of chrome, Molybdenum and nitrogen enhance resistance to adverse conditions in the presence of aggressive chemicals. They work consistently in offshore and marine. This would guarantee long life in industrial systems that are corrosive.
</li></ul></p><p><br></p><p><ul><li><b>Temperature and Pressure Capabilities:</b> Duplex Steel UNS S31803 Plates can be used successfully at a temperature of -50 o C to 300 o C under continuous operation. They are stable, mechanical and can withstand high-pressure conditions and cycles. Throughout the varying operating conditions, the material has resistance to thermal fatigue and deformation. This renders them to be applicable in heat exchangers and pressure vessels.
</li></ul></p><p><br></p><p><ul><li><b>Fabrication &amp; Industrial Applications:</b> The applications of these plates are broadly applied in oil and gas, petrochemical, desalination and power production industries. They can be welded and manufactured with controlled operations to preserve the properties of corrosion resistance. The customized engineering projects are facilitated by availability in different thicknesses. Such flexibility enables their use as a good solution to challenging structural and process applications.</li></ul><div><br></div><h3>Client Project Report of Duplex Steel UNS S31803 Plates</h3></p><div>
