Duplex Stainless Steel

The extrusion process plays an important role in the manufacturing of high-temperature alloys. The various processes during the extrusion process significantly impact the alloy’s microstructure and properties. This article will explore the effects of extrusion temperature, extrusion ratio, extrusion speed, ...

1 Overview In recent years, the output of the world’s duplex stainless steel is growing, accounting for about 1% to 2% of the total stainless steel production. The output of China’s duplex stainless steel has grown significantly with the production ...

The biphase in the name of the duplex stainless steel is mainly derived from the microstructure of the alloy. The duplex stainless steel usually contains about 50/50 austenite and delta ferrite phase mixture. Compared to austenitic stainless steel (for example, ...

In recent years, duplex stainless steel has not only been widely used in major oil companies, the main pipeline system development, and is the main material for offshore oil production and transportation. Standard duplex stainless steel in the sweet, wet, ...

Super Duplex Stainless Steel UNS S32760 (F55 / 1.4501) has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with Critical Pitting Temperature exceeding 50°C. Providing higher strength ...

Super Duplex 2507 (F53 / 1.4410 / UNS S32750) has excellent corrosion resistance to a wide variety of media, with outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with Critical Pitting Temperature exceeding 50°C.UNS ...

Deriving the Duplex name from the presence of both Austenite and Ferrite in similar proportions, Duplex Stainless Steels combine excellent corrosion resistance with high strength. The typical mechanical properties would be double that of a single phase austenitic grade such as 316, ...

Duplex 2304 is a 23‰ Cr, 4‰ Nickel, Mo free duplex stainless steel (23.04). We hold stock of duplex alloys in plate, flanges, pipes, and bars from our warehouse in the CN. We often meet specialist alloy profiling requirements and ...

Carbon steel suffer from ‘general’ corrosion, where large areas of the surface are affected. Stainless steel tubes in the passive state are normally protected against this form of attack, however, localised forms of attack can occur and result in corrosionproblems. The assessment ...

ASTM A790 covers seamless and straight-seam welded duplex stainless steel pipe for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. The duplex stainless steel pipe shall be made by the seamless or an automatic welding process, with no addition of ...
