Question 1

What are the main uses of Duplex 220 S32205 Round Bars?

Accepted Answer

Duplex 220 S32205 Round Bars are ideal for industries such as oil and gas, chemical processing, desalination plants, and pulp & paper mills. These bars offer outstanding resistance to stress corrosion, pitting, and crevice corrosion, especially in chloride-rich environments. Their strength and weldability make them suitable for load-bearing structures, pipelines, heat exchangers, and high-pressure applications.

Question 2

What standards are followed for manufacturing Duplex 220 Round Bars?

Accepted Answer

These round bars are manufactured according to ASTM A276, A479, and UNS S32205, ensuring consistency in mechanical and chemical performance. Standards regulate composition, tensile strength, yield properties, and tolerance limits. Our bars also meet client-specific requirements and are tested for ultrasonic defects, dimensional accuracy, and surface integrity before dispatch.

Question 3

Is it possible to order custom sizes and quantities for project-specific use?

Accepted Answer

Yes, Neptune Alloys offers full customization including diameter, length, tolerance, and finish based on your engineering drawings or material standards. We handle both small and bulk orders and provide comprehensive quality documentation such as Mill Test Certificates, third-party inspection reports, and packing with traceable heat numbers. This makes it easier to integrate our material into regulated industries and global supply chains.
