Duplex Steel 2205 Screw About

Duplex Steel 2205 Screw is an alloy of chromium, molybdenum, and nickel that provides excellent strength and corrosion resistance in marine and industrial atmospheres. This combination of properties makes Duplex Steel 2205 Screw a superb choice for many applications such as chemical process equipment, boilers, pressure vessels, pulp and paper handling equipment, piping systems for seawater systems, stainless steel valves and other rotary shafts.

Dual-Phase Strength and Corrosion Resistance

Duplex Steel 2205 Screws feature a balanced austenite-ferrite microstructure, delivering superior mechanical properties and enhanced corrosion resistance compared to conventional stainless steels. Their composition (21-23% Cr, 4.5-6.5% Ni, 2.5-3.5% Mo, 0.14-0.20% N) affords them outstanding resilience in marine, chemical, petrochemical, and outdoor environments.

Versatile Applications and Customization Options

Suitable for marine hardware, chemical processing, petrochemical plants, construction, piping, and mechanical assemblies, these screws are available in custom dimensions (diameter: M2-M36) and a variety of head and thread types. Finished in polished or passivated surfaces, they are provided in polybags, boxes, or custom packing as per client requirements.

Certified Quality and Reliable Supply

Compliant with ASTM A276, ASTM A479, and ISO 3506-1 standards, each batch of Duplex 2205 screws undergoes rigorous quality control. Ready stock and custom orders are available with flexible minimum order quantities to accommodate all project scales.

FAQ's of Duplex Steel 2205 Screw:

Q: How are Duplex Steel 2205 Screws suitable for marine and industrial environments?

A: Duplex Steel 2205 Screws offer excellent resistance to pitting, crevice, and stress corrosion thanks to their high chromium, molybdenum, and nitrogen content. Their robust duplex microstructure ensures durability in aggressive marine, chemical, and industrial conditions, making them ideal for outdoor and corrosion-prone applications.

Q: What thread and head types are available for Duplex Steel 2205 Screws?

A: These screws are manufactured in Metric, UNC, and UNF thread types, and come with various head options including Phillips, Slotted, Hex, and Torx to suit different installation and design requirements.

Q: When should I use Duplex 2205 over conventional stainless steel screws?

A: Choose Duplex 2205 when you require greater tensile strength and outstanding corrosion resistance, especially in environments exposed to seawater, chemicals, or temperature fluctuations. Their performance surpasses standard stainless steels under such demanding conditions.

Q: Where can I specify custom dimensions or finishes for my screw order?

A: Custom sizes (length, width, diameter) and finishes (bright, matte, polished, or passivated) can be specified during order placement. Your requirements are accommodated whether you're sourcing for unique machinery, construction, or high-precision assemblies.

Q: What is the minimum order quantity for Duplex Steel 2205 Screws?

A: The minimum order quantity is flexible and set according to the client's project requirements, ensuring efficiency whether you need bulk supply or small, specialized batches.

Q: How are Duplex 2205 Screws packed and shipped to ensure quality?

A: Screws are packed in polybags, boxes, or custom packaging to protect against physical and environmental damage during transit. This ensures that the products arrive in excellent condition, ready for immediate use or storage.

Q: What are the benefits of using Duplex Steel 2205 Screws in terms of heat resistance and magnetic properties?

A: These screws maintain structural integrity and resist corrosion up to temperatures of 300C. They are slightly magnetic due to their duplex structure, which can be beneficial or negligible depending on specific application requirements.
