Duplex steel S32750 sheet is a popular type of duplex stainless steel sheet that is highly resistant to corrosion and oxidation. It is also known as super duplex steel due to its high strength and toughness. This type of steel sheet is widely used in various industries that require high-quality materials to withstand harsh environmental conditions.

Duplex steel S32750 is made up of a combination of austenitic and ferritic stainless steel, which provides it with excellent corrosion resistance and high strength. The presence of chromium, molybdenum, and nitrogen in the steel makes it highly resistant to pitting and crevice corrosion, even in harsh saltwater environments.

One of the key advantages of duplex steel S32750 sheet is its high yield strength. This property makes it an ideal material for use in applications that require a high level of durability and strength, such as offshore oil and gas drilling platforms, chemical processing plants, and naval vessels. The material is also resistant to stress corrosion cracking, which makes it well-suited for applications that experience high levels of stress and pressure.

Another key property of duplex steel S32750 sheet is its resistance to thermal expansion and contraction. This property makes it an ideal choice for high-temperature applications, such as heat exchangers, boilers, and piping systems.

Physical Properties:
- Density: 7.8 g/cm3
- Thermal conductivity: 14.2 W/m-K
- Electrical resistivity: 0.8 μΩ-m
- Specific heat capacity: 460 J/kg-K
- Melting point: 1350 – 1450°C

Due to its exceptional strength, durability, and corrosion resistant properties, duplex steel S32750 sheet is more expensive than other types of stainless steel. However, its long-term benefits in terms of extended service life and reduced maintenance costs make it a cost-effective option in the long run.

In conclusion, duplex steel S32750 sheet is a high-quality material known for its excellent corrosion resistance, high strength, and toughness. It is widely used in various industries that require materials that can withstand harsh environmental conditions, high stress, and temperature. Its exceptional properties make it a valuable investment for any application that requires high-quality materials in the long run.
