Duplex Steel Strips

Duplex steel strips combine austenitic and ferritic stainless steel, giving it strength and corrosion resistance. These strips are known for their high resistance to stress corrosion cracking, pitting and crevice corrosion, which makes them suitable for various industrial applications. The microstructure of duplex steel makes it have desirable mechanical properties and corrosion resistance when used in conditions that are unforgiving and at high pressures.

Features of Duplex steel strips 

Key features of Duplex steel strips include:

• High Strength: Duplex steel's mechanical properties are far better than those of standard austenitic or ferritic steels, so thinner and lighter strips can be fabricated.
• Corrosion Resistance: These strips are very resistant to corrosion, such as pitting, crevice and stress corrosion cracking.
• Good Weldability: Duplex Steel Strips are highly weldable and flexible for use in various industries as they do not require a lot of structural changes after the welding process.
• Enhanced Durability: The fusion of the austenitic and the ferritic structures provides the material with high levels of toughness and service life, irrespective of temperature and pressure.
• Cost-Effective: Duplex Steel Strips are the long-term solutions to the problems associated with using thick materials and constant replacements in corrosive atmospheres.

Such characteristics make Duplex Steel Strips ideal for various challenging operations within industries.

Uses of Duplex Steel Strips

Duplex Steel Strips have extensive applications in different fields because of their great characteristics. Key applications include:

• Chemical Processing: Duplex steel strips manufacture equipment such as heat exchangers, pressure vessels and storage tanks.
• Oil and Gas Industry: These strips are recommended for pipelines, flowlines, and offshore platforms because they are resistant to marine environments.
• Marine Industry: Duplex steel strips are used in ship construction, water desalination, and marine facility construction due to their resistance to seawater corrosion.
• Pulp and Paper Industry: Duplex steel strips are applied in the machinery that comes into contact with aggressive chemical in the pulping stage of the process.
• Construction: Duplex steel strips are applied to structures of facades, bridges and various structural members where high strength and corrosion resistance to pressure are required.
• Pharmaceuticals: The strips are used in manufacturing equipment that does not allow contamination while withstanding chemical erosion from drug processing.
• Automotive and Transportation: Duplex steel strips are used in exhaust systems, fuel lines, and other structural components.

This application shows that Duplex Steel Strips are used across various industries that require consistent performance in challenging conditions.
