Super Duplex Steel Plates are made of an alloy mixture of chromium, nickel, molybdenum, copper, and nitrogen. This combination creates a material that is harder and more resistant to corrosion than other traditional steels. The chromium contributes to higher resistance for the steel against localized corrosive environments. Nickel helps to improve weldability and toughness. Molybdenum enhances the pitting resistance and allows for good comprehensive strength in low-temperature settings. Copper is added to allow for more toughness in the particles. Lastly, nitrogen increases this special metal material's mechanical strength and weldability.
Super Duplex Steel Plates are often used in applications that require superior strength and corrosion resistance. The Super Duplex material combines the properties of both austenitic and ferritic stainless plates of steel, making it an incredibly versatile alloy. It has excellent tensile strength and good stress corrosion cracking resistance and pitting and crevice corrosion resistance. Due to its additive composition, it also boasts exceptional weldability compared to other duplex grades. It is appreciated for its wide array of uses and its affordability, making it a popular choice for various industries such as oil & gas, petrochemical, marine engineering, offshore engineering jobs, and much more.
Yes, Super Duplex Steel Plates are considered to be Eco-friendly. The materials used in the manufacturing process of these plates do not contain any hazardous substances that could harm the environment.
The grade of a Super Duplex Steel Plate can be identified by looking at its chemical composition and mechanical properties. Generally speaking, higher grades tend to have better mechanical properties, such as higher yield strength, better impact resistance and more corrosion resistance.
Testing is an important part of quality control when it comes to Super Duplex Steel Plates. Depending on the product and its intended purpose, different tests are used, such as tensile tests, hardness tests, metallographic examination, non-destructive testing, or pressure testing.
