Overview of Duplex Steel Strip

Duplex steel strip is a product of a special grade of stainless steel whose microstructure is of the dual phase type with a relative constant proportion of austenite and ferrite. This is a balanced form that has the best characteristics of both phases that provides greater mechanical strength than austenitic stainless steels and greater corrosion resistance than ferritic grades.

Duplex steel strips are extensively applied in the environments where there are chlorides, moisture, aggressive chemicals, and mechanical stress. They are very effective in stress corrosion cracking and thus are suitable in extreme industrial, chemical and marine work.

Key Material Properties

The steel strips are duplex and offer a good compromise of strength, resistance to corrosion and cost effectiveness compared to the traditional stainless steel materials.

Key material properties include:

  • High yield and tensile strength
  • Excellent resistance to pitting and crevice corrosion
  • Superior resistance to stress corrosion cracking
  • Good weldability with appropriate fabrication practices
  • High fatigue strength
  • Strong performance in chloride-rich environments
  • Long service life with reduced maintenance requirements

These qualities render duplex steel strips to be used in high load, high pressure and corrosive service environments.

Material Specifications

  • Thickness Range: 0.3 mm to 6.0 mm
  • Width: Up to 1250 mm (custom widths available)
  • Standards: ASTM A240, ASTM A480, EN 10088
  • Grades: UNS S31803, S32205 (2205), S32750, S32760
  • Surface Finish: 2B, BA, No.1, No.4
  • Condition: Hot Rolled (HR), Cold Rolled (CR)
  • Edge: Mill edge, slit edge

Any duplex steel strips are manufactured according to the world chemical and mechanical standards.

Industrial Applications

Duplex steel strips are widely applied in industries where extreme strength is needed in addition to high corrosion resistance. Their common uses are heat exchangers, pressure vessels, chemical processing equipment, storage tanks, oil and gas parts, marine hardware, desalination, pulp and paper machines, and power generation.

Duplex steel strip has demonstrated its effectiveness in aggressive environments, so it is a popular solution to safety-critical and performance-driven fabrications in the industry.

Manufacturing Excellence

We are a Duplex Steel Strip Manufacturer with extensive experience, so we pay attention to the fact that the chemical composition, rolling parameters, and phase balance are closely controlled when we produce something. Newer manufacturing methods guarantee good uniformity of thickness, high-quality surface and mechanical consistency.

The duplex steel strips are strictly tested in terms of quality, chemical tests, mechanical tests, dimensional checks, and non-destructive testing so that the complete compliance to the global standards can be achieved.
