Super Duplex Steel Forging is the process in which steel is formed under high temperature and pressure to produce high-tensile parts. They have developed high-performance alloys that are a blend of ferritic and austenitic stainless steel. These alloys normally consist of about 50% austenite and 50% ferrite to offer higher strength, high corrosion resistance, and enhanced toughness. This steel forging produces valves, flanges, shafts, and fittings capable of handling high-stress and corrosive environments.
Features of Super Duplex Steel Forging
These flexible Super Duplex Steel Forgings offer numerous benefits for industrial applications.
- Exceptional Strength: Super duplex steel is stronger mechanically than other stainless steels, and the forged parts are stronger and more resistant to mechanical wear.
- Superior Corrosion Resistance: Super duplex steel offers good protection against pitting, crevice corrosion, and stress corrosion cracking in seawater or acidic solutions.
- High Toughness and Ductility: Super duplex steel, though very strong, has good ductility and toughness, thus the forged parts are suitable for high pressure and fluctuating temperatures.
- Resistance to Chloride Attack: This forging is especially suitable for applications where the component may be exposed to chlorides to minimise the chance of corrosive attack and subsequent failure.
- Improved Cost Efficiency: It has high strength, so thinner parts can be used while retaining the same level of strength, which saves material and weight.
- High Heat Resistance: Super duplex steel does not degrade in high temperatures and is thus ideal for use in conditions where temperatures are likely to vary or are high.
- Weldability: Super duplex steel components exhibit good weldability, which is important for achieving good welds during installation or fabrication.
- Fatigue Resistance: Super duplex steel offers good fatigue strength and is desirable for applications where the component will be subjected to dynamic or cyclic loading.
- Longevity: Corrosion protection, strength, and toughness make it possible to have extended service parts that do not require constant replacements hence saving operational expenses.
- Dimensional Accuracy: Forging allows for more accurate shapes of components that will fit well in critical applications, thus increasing productivity and reliability.
Super Duplex Steel Forgings offer several advantages that make them suitable for industrial and commercial applications.
