Incoloy 28 polished bar
Incoloy 28 polished bar is a nickel-iron-chromium based superaustenitic stainless steel. Adding molybdenum and copper greatly improves its corrosion resistance. It has about 31% nickel, about 27% chromium, about 3.5% molybdenum. It also has a small amount of copper and nitrogen. It is finely processed and has a mirror or near-mirror finish. It has high dimensional accuracy. It is used in fields that have strict requirements for surface quality and corrosion resistance.
Incoloy 28 polished bar is widely used in many fields. In the chemical industry, it is used in acid cleaning equipment and pipelines. In marine engineering, it is used in seawater desalination systems and pump valves. In the energy field, it is used in oil and gas downhole tools and geothermal equipment. In the environmental protection field, it is used in flue gas desulfurization devices.
Incoloy 28 polished bar has excellent corrosion resistance, high strength and polished surface characteristics. It is a key material in extremely corrosive environments. It can greatly extend the life of parts and reduce maintenance costs.
Features of Incoloy 28 polished bar
Excellent corrosion resistance: Incoloy 28 polished bar performs well in acidic, chloride, and high-temperature, high-pressure environments such as sulfuric acid, phosphoric acid, and seawater. It has much better resistance to pitting and stress corrosion cracking than regular stainless steel.
High mechanical strength: Incoloy 28 polished bar has good ductility and toughness. It is suitable for high-stress working conditions.
Advantages of polishing: The smooth surface of Incoloy 28 polished bar reduces dirt adhesion. It lowers the risk of corrosion and also improves appearance.
Good weldability: Incoloy 28 polished bar can be welded by common methods. It still keeps its corrosion resistance after welding.

Applications of Incoloy 28 polished bar
Chemical industry: Incoloy 28 polished bar is used to make sulfuric acid recovery units, acid cleaning equipment, and piping systems.
Marine engineering: Incoloy 28 polished bar is used in high-pressure pipes and pump valve components of seawater desalination plants.
Energy sector: Incoloy 28 polished bar is used in downhole tools for oil and gas extraction and geothermal fluid processing equipment.
Environmental protection equipment: Incoloy 28 polished bar is used to make key parts of flue gas desulfurization systems (FGD).
