Pipingmaterial.ae introducing genuine and verified duplex flat bar and square bar suppliers in Dubai
Is duplex steel rod suitable for seawater?
The duplex steel rod has a microstructure of two phases- Ferritic and Austenitic. The composition of Duplex steel has more Chromium and Molybdenum. The above properties make the alloy highly resistant to corrosive environments, especially salt water. Hence, they are popularly applicable in desalination systems, pipes, and pumps with saltwater exposure.

What should I check before dealing with suppliers or manufacturers?
Before you buy a duplex square bar from a manufacturer or supplier you must ensure that they are genuine. The best way to find verified manufacturers is via pipingmaterial.ae website. You can get all the necessary certificates about the round bar on the website of each supplier.
It is ideal to recheck all the test certificates, like ASTM standards, Tensile tests, Hardness tests, Metallography, PMI, DPI, Ultrasonic Testing, Radiography, etc. You must also ensure they have a raw material testing certificate for quality assurance.

What is the strain hardening condition in a duplex stainless steel bar?
Strain hardening of a duplex stainless steel bar refers to work hardening. The alloy cannot undergo heat treatment; however work hardening of the material at low temperatures is possible. The process produces mechanical deformation due to smaller cross-section and lower ductility. However, the corrosion resistance and strength of the material improves.

Rolled vs forged bar
The rolled duplex steel bar is the result of a hot-rolling or cold-rolling process. The hot-rolling involves heating the duplex stainless steel above its recrystallization temperature. It improves the mechanical properties and shapes of the material. The cold-rolling process involves bringing the hot-rolled duplex bar to room temperature and processing it further. It provides precision, hardness, smooth surface finish, etc.
The forged duplex stainless steel flat bar is the result of heating the alloy at extreme temperatures, called Forging. It induces high strength, corrosion resistance, ductility, and toughness. They are economical; hence applicable in industries, like chemical processing, petrochemical, oil, and gas, etc.
Duplex steel round bar vs shaft
The duplex stainless steel round bar has great strength and resistance against pitting and stress-cracking corrosion. They have great impact strength and heat resistance. Hence, are applicable in the construction and heating industries.
Shafts are materials applicable in the construction industry. Duplex steel shaft is the ideal material as they have great strength, corrosion resistance and impact resistance.
