Advantages of Duplex Steel Bars

  • Water resistance: Duplex steel bars offer better corrosion resistance compared to conventional austenitic stainless steel, especially in chloride, acidic seawater environments
  • High strength: Duplex steel bars have higher tensile and yield strength compared to austenitic stainless steel, making them suitable for applications requiring high mechanical properties
  • Highly durable: The two-dimensional steel exhibits good strength and flexibility even at low temperatures, making it suitable for use in harsh environments and cryogenic environments
  • Cost Effectiveness: Despite having excellent properties, double-sided steel frames can be more cost-effective than other stainless steel alloys, striking a balance between performance and price between the strong
  • Good weldability: Duplex steel bars usually have good weldability, making them easy to manufacture and fabricate in various applications without compromising structural integrity
  • Stress Corrosion Crack Resistance: Duplex steel bars exhibit superior resistance to stress corrosion cracking (SCC), a common phenomenon in many corrosive environments, ensuring long service life and reliability
  • Abrasion Resistance: Duplex steel bars resist abrasion and erosion, making them suitable for use in industries such as mining, chemical processing, and oil & gas where abrasive media are present.
  • Multiple applications: Dual metals find applications in a wide range of industries, including chemical processing, oil and gas, marine, pulp and paper, and desalination, and mean versatility and adaptability to different environments and needs

  • Water resistance: Evaluate the corrosion resistance of the duplex steel and select the grade of corrosion resistance required, such as pitting, crevice corrosion, and stress corrosion cracking, based on the environmental exposure between them (e.g., seawater, chemicals, acids ).
  • Mechanical properties: Consider the required mechanical properties of duplex steel, including tensile strength, yield strength, stretchability, and shock resistance. Select the grade of strength and stiffness you wish to use.
  • Weldability: If your application involves welding or fabrication processes, consider the weldability of duplex steel bars. Select a grade with good weldability to ensure easy installation and maintain the integrity of welded joints.
  • Availability and cost: Determine the availability and price of duplex steel frames by considering factors such as market demand, supply, supply, price fluctuations, etc. Balance within the business needs and budget constraints of your application.
  • Industry Standards and Specifications: Ensure duplex steel conforms to appropriate industry standards and specifications, such as ASTM, ASME, EN, and others, to ensure quality, conformity, and compliance with regulatory requirements.

Can Duplex Steel Bars be recycled after use?

Yes, Duplex stainless steel bars can be recycled after use. Stainless steel, including Duplex steel, is highly recyclable and can be melted down and reused to make new products without losing its inherent properties. Recycling stainless steel is a sustainable practice that helps conserve resources and reduces the environmental impact of mining and manufacturing new materials. Additionally, the recycling process for stainless steel requires less energy than producing new stainless steel from raw materials, making it an environmentally friendly choice.

FAQ (Frequently Asked Questions)

Can Duplex Steel Bars be welded?

Yes, Duplex Steel Bars can be welded using common welding methods such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), shielded metal arc welding (SMAW), and submerged arc welding (SAW). However, it’s important to follow proper welding procedures to maintain the material’s corrosion resistance and mechanical properties.

How do Duplex Steel Bars compare to other stainless steel grades?

Duplex Steel Bars offer advantages over austenitic stainless steels in higher strength and better resistance to stress corrosion cracking, especially in chloride environments. Duplex Steel Bars have superior toughness and flexibility compared to ferritic stainless steel.

What precautions should be taken when machining Duplex Steel Bars?

Machining Duplex Steel Bars require adequate cooling and lubrication to minimize heat buildup and avoid work hardening. Additionally, selecting appropriate cutting tools and maintaining proper cutting speeds and feeds are essential to achieve good surface finish and dimensional accuracy.
