Super Duplex Stainless Steel Plate

Super duplex stainless steel plates are highly durable and resistant to corrosion, making them an ideal choice for use in harsh environments. At Om Steel, we offer a wide range of super duplex stainless steel plates that are designed to meet the unique needs of our clients.

Super duplex stainless steel plates are made up of a combination of austenitic and ferritic stainless steel, which provides them with exceptional strength and resistance to corrosion. These plates have higher chromium, molybdenum, and nitrogen content than standard duplex stainless steel plates, which provides them with superior corrosion resistance and higher strength.

At Om Steel, we offer various grades of super duplex stainless steel plates, including S32750, S32760, S32550, and others. These grades have different properties and are used in various applications based on their strength, corrosion resistance, and other factors. For instance, S32750 is a high-strength grade that is commonly used in oil and gas industry applications, while S32760 is a super duplex grade with excellent corrosion resistance that is often used in marine and chemical processing industries.

Super duplex stainless steel plates also offer excellent heat resistance, making them suitable for high-temperature applications. They are highly versatile and can be used in various industrial applications, including oil and gas, chemical processing, and desalination.

Chequered and Thin Plates, Hot Rolled Sheets, and Perforated Plates of Super Duplex Stainless Steel

Super duplex stainless steel is a highly durable alloy that is widely used in various industries. It has excellent corrosion resistance properties and can withstand high temperatures, making it suitable for use in harsh environments. Chequered and thin plates, hot rolled sheets, and perforated plates are some of the most popular forms of super duplex stainless steel.

Chequered Plates

Chequered plates are also known as tread plates or floor plates. They have a raised surface pattern that provides excellent slip resistance. These plates are commonly used in industrial flooring applications where safety is a top priority. The raised pattern on the surface creates friction between the plate and the footwear, reducing the risk of slips and falls.

Thin Plates

Thin plates are flat sheets of super duplex stainless steel that are less than 3mm thick. They are commonly used in applications where weight is a concern, such as aerospace or automotive industries. Thin plates offer high strength-to-weight ratios while maintaining excellent corrosion resistance properties.

Hot Rolled Sheets

Hot rolled sheets are produced by rolling heated slabs of super duplex stainless steel through a series of rollers to achieve the desired thickness. This process results in sheets with uniform thicknesses and smooth surfaces. Hot rolled sheets have excellent thermal conductivity properties, making them ideal for use in heat exchangers or other high-temperature applications.

Perforated Plates

Perforated plates are sheets of super duplex stainless steel that have been punched with holes to create a patterned surface. The holes can be round, square, or any other shape depending on the application requirements. Perforated plates offer several benefits such as improved ventilation and reduced weight while maintaining structural integrity.

Properties of Super Duplex Stainless Steel Plates

Tensile Strength

One of the most significant mechanical properties of super duplex stainless steel plates is their high tensile strength. Tensile strength refers to the maximum amount of stress that a material can withstand before breaking or fracturing. The tensile strength of super duplex stainless steel plates ranges from 620 MPa to 900 MPa, depending on the grade and thickness of the plate.

Yield Strength

Another important mechanical property of super duplex stainless steel plates is their yield strength. Yield strength refers to the amount of stress that a material can withstand without undergoing permanent deformation. The yield strength of super duplex stainless steel plates ranges from 450 MPa to 650 MPa, depending on the grade and thickness of the plate.

Elongation

Elongation is another crucial mechanical property that determines how much a material can stretch before it breaks. Super duplex stainless steel plates have an elongation range between 25% to 30%, which indicates its ability to deform under tension without breaking.

Hardness

Super duplex stainless steel plates also exhibit excellent hardness levels due to their high chromium and molybdenum content. Hardness refers to a material’s ability to resist indentation or scratching by another object. The hardness level varies based on grades and thicknesses, ranging from Brinell hardness (HB) 250-290 for thinner sheets up to HB350-380 for thicker ones.

Impact Toughness

The impact toughness measures how well a material can absorb energy during sudden impacts or shocks without breaking or cracking. Super duplex stainless steel has excellent impact toughness compared with other types of stainless steel. The impact toughness of super duplex stainless steel plates is around 100 J at room temperature, which makes them highly resistant to sudden impacts.

Fatigue Strength

The fatigue strength of a material refers to its ability to withstand cyclic loading without failing or breaking. Super duplex stainless steel plates have excellent fatigue strength due to their high tensile and yield strengths, making them ideal for use in applications that require durability and longevity.

Corrosion Resistance

Super duplex stainless steel plates are known for their exceptional corrosion resistance properties. They exhibit superior resistance against various types of corrosion, including pitting, crevice, and stress corrosion cracking. This property makes them highly desirable in harsh environments where other materials would fail due to corrosion.
